Set version to 0.26.4-sp1

Fix account_lines, account_offers and book_offers result (RIPD-682):
The RPC account_lines and account_offers commands respond with the correct ledger info. account_offers, account_lines and book_offers allow admins unlimited size on the limit param. Specifying a negative value on limit clamps to the minimum value allowed. Incorrect types for limit are correctly reported in the result.

 # Coding Standards

-Coding standards used here are extreme strict and consistent. The style
-evolved gradually over the years, incorporating generally acknowledged
-best-practice C++ advice, experience, and personal preference.
+Coding standards used here gradually evolve and propagate through 
+code reviews. Some aspects are enforced more strictly than others.

-## Don't Repeat Yourself!
+## Rules

-The [Don't Repeat Yourself][1] principle summarises the essence of what it
-means to write good code, in all languages, at all levels.
+These rules only apply to our own code. We can't enforce any sort of 
+style on the external repositories and libraries we include. The best
+guideline is to maintain the standards that are used in those libraries.
+
+* Tab inserts 4 spaces. No tab characters.
+* Braces are indented in the [Allman style][1].
+* Modern C++ principles. No naked ```new``` or ```delete```.
+* Line lengths limited to 80 characters. Exceptions limited to data and tables.
+
+## Guidelines
+
+If you want to do something contrary to these guidelines, understand
+why you're doing it. Think, use common sense, and consider that this
+your changes will probably need to be maintained long after you've
+moved on to other projects.
+
+* Use white space and blank lines to guide the eye and keep your intent clear.
+* Put private data members at the top of a class, and the 6 public special
+members immediately after, in the following order:
+  * Destructor
+  * Default constructor
+  * Copy constructor
+  * Copy assignment
+  * Move constructor
+  * Move assignment
+* Don't over-inline by defining large functions within the class
+declaration, not even for template classes.

@@ -62,156 +83,4 @@ overlooked. Blank lines are used to separate code into "paragraphs."
 * Always place a space in between the template angle brackets and the type
  name. Template code is already hard enough to read!

-## Naming conventions
-
-* Member variables and method names are written with camel-case, and never
-  begin with a capital letter.
-* Class names are also written in camel-case, but always begin with a capital
-  letter.
-* For global variables... well, you shouldn't have any, so it doesn't matter.
-* Class data members begin with `m_`, static data members begin with `s_`.
-  Global variables begin with `g_`. This is so the scope of the corresponding
-  declaration can be easily determined.
-* Avoid underscores in your names, especially leading or trailing underscores.
-  In particular, leading underscores should be avoided, as these are often used
-  in standard library code, so to use them in your own code looks quite jarring.
-* If you really have to write a macro for some reason, then make it all caps,
-  with underscores to separate the words. And obviously make sure that its name
-  is unlikely to clash with symbols used in other libraries or 3rd party code.
-
-## Types, const-correctness
-
-* If a method can (and should!) be const, make it const!
-* If a method definitely doesn't throw an exception (be careful!), mark it as
-  `noexcept`
-* When returning a temporary object, e.g. a String, the returned object should
-  be non-const, so that if the class has a C++11 move operator, it can be used.
-* If a local variable can be const, then make it const!
-* Remember that pointers can be const as well as primitives; For example, if
-  you have a `char*` whose contents are going to be altered, you may still be
-  able to make the pointer itself const, e.g. `char* const foobar = getFoobar();`.
-* Do not declare all your local variables at the top of a function or method
-  (i.e. in the old-fashioned C-style). Declare them at the last possible moment,
-  and give them as small a scope as possible.
-* Object parameters should be passed as `const&` wherever possible. Only
-  pass a parameter as a copy-by-value object if you really need to mutate
-  a local copy inside the method, and if making a local copy inside the method
-  would be difficult.
-* Use portable `for()` loop variable scoping (i.e. do not have multiple for
-  loops in the same scope that each re-declare the same variable name, as
-  this fails on older compilers)
-* When you're testing a pointer to see if it's null, never write
-  `if (myPointer)`. Always avoid that implicit cast-to-bool by writing it more
-  fully: `if (myPointer != nullptr)`. And likewise, never ever write
-  `if (! myPointer)`, instead always write `if (myPointer == nullptr)`.
-  It is more readable that way.
-* Avoid C-style casts except when converting between primitive numeric types.
-  Some people would say "avoid C-style casts altogether", but `static_cast` is
-  a bit unreadable when you just want to cast an `int` to a `float`. But
-  whenever a pointer is involved, or a non-primitive object, always use
-  `static_cast`. And when you're reinterpreting data, always use
-  `reinterpret_cast`.
-* Until C++ gets a universal 64-bit primitive type (part of the C++11
-  standard), it's best to stick to the `int64` and `uint64` typedefs.
-
-## Object lifetime and ownership
-
-* Absolutely do NOT use `delete`, `deleteAndZero`, etc. There are very very few
-  situations where you can't use a `ScopedPointer` or some other automatic
-  lifetime management class.
-* Do not use `new` unless there's no alternative. Whenever you type `new`, always
-  treat it as a failure to find a better solution. If a local variable can be
-  allocated on the stack rather than the heap, then always do so.
-* Do not ever use `new` or `malloc` to allocate a C++ array. Always use a
-  `HeapBlock` instead.
-* And just to make it doubly clear: Never use `malloc` or `calloc`.
-* If a parent object needs to create and own some kind of child object, always
-  use composition as your first choice. If that's not possible (e.g. if the
-  child needs a pointer to the parent for its constructor), then use a
-  `ScopedPointer`.
-* If possible, pass an object as a reference rather than a pointer. If possible,
-  make it a `const` reference.
-* Obviously avoid static and global values. Sometimes there's no alternative,
-  but if there is an alternative, then use it, no matter how much effort it
-  involves.
-* If allocating a local POD structure (e.g. an operating-system structure in
-  native code), and you need to initialise it with zeros, use the `= { 0 };`
-  syntax as your first choice for doing this. If for some reason that's not
-  appropriate, use the `zerostruct()` function, or in case that isn't suitable,
-  use `zeromem()`. Don't use `memset()`.
-
-## Classes
-
-* Declare a class's public section first, and put its constructors and
-  destructor first. Any protected items come next, and then private ones.
-* Use the most restrictive access-specifier possible for each member. Prefer
-  `private` over `protected`, and `protected` over `public`. Don't expose
-  things unnecessarily.
-* Preferred positioning for any inherited classes is to put them to the right
-  of the class name, vertically aligned, e.g.:
-        class Thing  : public Foo, 
-                       private Bar
-        {
-        }
-* Put a class's member variables (which should almost always be private, of course),
-  after all the public and protected method declarations.
-* Any private methods can go towards the end of the class, after the member
-  variables.
-* If your class does not have copy-by-value semantics, derive the class from
-  `Uncopyable`.
-* If your class is likely to be leaked, then derive your class from
-  `LeakChecked<>`.
-* Constructors that take a single parameter should be default be marked
-  `explicit`. Obviously there are cases where you do want implicit conversion,
-  but always think about it carefully before writing a non-explicit constructor.
-* Do not use `NULL`, `null`, or 0 for a null-pointer. And especially never use
-  '0L', which is particulary burdensome. Use `nullptr` instead - this is the
-  C++2011 standard, so get used to it. There's a fallback definition for `nullptr`
-  in Beast, so it's always possible to use it even if your compiler isn't yet
-  C++2011 compliant.
-* All the C++ 'guru' books and articles are full of excellent and detailed advice
-  on when it's best to use inheritance vs composition. If you're not already
-  familiar with the received wisdom in these matters, then do some reading!
-
-## Miscellaneous
-
-* `goto` statements should not be used at all, even if the alternative is
-  more verbose code. The only exception is when implementing an algorithm in
-  a function as a state machine.
-* Don't use macros! OK, obviously there are many situations where they're the
-  right tool for the job, but treat them as a last resort. Certainly don't ever
-  use a macro just to hold a constant value or to perform any kind of function
-  that could have been done as a real inline function. And it goes without saying
-  that you should give them names which aren't going to clash with other code.
-  And `#undef` them after you've used them, if possible.
-* When using the `++` or `--` operators, never use post-increment if
-  pre-increment could be used instead. Although it doesn't matter for
-  primitive types, it's good practice to pre-increment since this can be
-  much more efficient for more complex objects. In particular, if you're
-  writing a for loop, always use pre-increment,
-  e.g. `for (int = 0; i < 10; ++i)`
-* Never put an "else" statement after a "return"! This is well-explained in the
-  LLVM coding standards...and a couple of other very good pieces of advice from
-  the LLVM standards are in there as well.
-* When getting a possibly-null pointer and using it only if it's non-null, limit
-  the scope of the pointer as much as possible - e.g. Do NOT do this:
-
-        Foo* f = getFoo ();
-        if (f != nullptr)
-            f->doSomething ();
-        // other code
-        f->doSomething ();  // oops! f may be null!
-
-  ..instead, prefer to write it like this, which reduces the scope of the
-  pointer, making it impossible to write code that accidentally uses a null
-  pointer:
-
-        if (Foo* f = getFoo ())
-            f->doSomethingElse ();
-
-        // f is out-of-scope here, so impossible to use it if it's null
-
-  (This also results in smaller, cleaner code)

+## Heap profiling of rippled with jemalloc
+
+The jemalloc library provides a good API for doing heap analysis,
+including a mechanism to dump a description of the heap from within the
+running application via a function call. Details on how to perform this
+activity in general, as well as how to acquire the software, are available on
+the jemalloc site:
+[https://github.com/jemalloc/jemalloc/wiki/Use-Case:-Heap-Profiling](https://github.com/jemalloc/jemalloc/wiki/Use-Case:-Heap-Profiling)
+
+jemalloc is acquired separately from rippled, and is not affiliated
+with Ripple Labs. If you compile and install jemalloc from the
+source release with default options, it will install the library and header
+under `/usr/local/lib` and `/usr/local/include`, respectively. Heap
+profiling has been tested with rippled on a Linux platform. It should
+work on platforms on which both rippled and jemalloc are available.
+
+To link rippled with jemalloc, the argument
+`profile-jemalloc=<jemalloc_dir>` is provided after the optional target.
+The `<jemalloc_dir>` argument should be the same as that of the
+`--prefix` parameter passed to the jemalloc configure script when building.
+
+## Examples:
+
+Build rippled with jemalloc library under /usr/local/lib and
+header under /usr/local/include:
+
+    $ scons profile-jemalloc=/usr/local
+
+Build rippled using clang with the jemalloc library under /opt/local/lib
+and header under /opt/local/include:
+
+    $ scons clang profile-jemalloc=/opt/local
+
+----------------------
+
+## Using the jemalloc library from within the code
+
+The `profile-jemalloc` parameter enables a macro definition called
+`PROFILE_JEMALLOC`. Include the jemalloc header file as
+well as the api call(s) that you wish to make within preprocessor
+conditional groups, such as:
+
+In global scope:
+
+    #ifdef PROFILE_JEMALLOC
+    #include <jemalloc/jemalloc.h>
+    #endif
+
+And later, within a function scope:
+
+    #ifdef PROFILE_JEMALLOC
+    mallctl("prof.dump", NULL, NULL, NULL, 0);
+    #endif
+
+Fuller descriptions of how to acquire and use jemalloc's api to do memory
+analysis are available at the [jemalloc
+site.](http://www.canonware.com/jemalloc/)
+
+Linking against the jemalloc library will override
+the system's default `malloc()` and related functions with jemalloc's
+implementation. This is the case even if the code is not instrumented
+to use jemalloc's specific API.

-Don't Repeat Yourself, <20>D.R.Y.<2E>. Put redundant code in a class so it can be re-used and unit tested.
-Expose as little of a class as possible. Prefer private over protected. Prefer protected over public. The smaller the interface footprint, the easier it is to write unit tests and comprehend the operation of the class. This is the Interface Segregation Principle.
-Use language constants (enum or static const) with descriptive names instead of hard-coded <20>magic numbers.<2E>
-Make classes depend on as few external classes or routines as possible. Ideally, no dependencies.
-Don't limit flexibility of parameters by forcing the caller to use specific types where general types would work.

-
-# Coding Standards
-
-Coding standards used here are extreme strict and consistent. The style
-evolved gradually over the years, incorporating generally acknowledged
-best-practice C++ advice, experience, and personal preference.
-
-## Don't Repeat Yourself!
-
-The [Don't Repeat Yourself][1] principle summarises the essence of what it
-means to write good code, in all languages, at all levels.
-
-## Formatting
-
-The goal of source code formatting should always be to make things as easy to
-read as possible. White space is used to guide the eye so that details are not
-overlooked. Blank lines are used to separate code into "paragraphs."
-
-* No tab characters please.
-* Tab stops are set to 4 spaces.
-* Braces are indented in the [Allman style][2].
-* Always place a space before and after all binary operators,
-  especially assignments (`operator=`).
-* The `!` operator should always be followed by a space.
-* The `~` operator should be preceded by a space, but not followed by one.
-* The `++` and `--` operators should have no spaces between the operator and
-  the operand.
-* A space never appears before a comma, and always appears after a comma.
-* Always place a space before an opening parenthesis. One exception is if
-  the parentheses are empty.
-* Don't put spaces after a parenthesis. A typical member function call might
-  look like this: `foobar (1, 2, 3);`
-* In general, leave a blank line before an `if` statement.
-* In general, leave a blank line after a closing brace `}`.
-* Do not place code or comments on the same line as any opening or
-  closing brace.
-* Do not write `if` statements all-on-one-line. The exception to this is when
-  you've got a sequence of similar `if` statements, and are aligning them all
-  vertically to highlight their similarities.
-* In an `if-else` statement, if you surround one half of the statement with
-  braces, you also need to put braces around the other half, to match.
-* When writing a pointer type, use this spacing: `SomeObject* myObject`.
-  Technically, a more correct spacing would be `SomeObject *myObject`, but
-  it makes more sense for the asterisk to be grouped with the type name,
-  since being a pointer is part of the type, not the variable name. The only
-  time that this can lead to any problems is when you're declaring multiple
-  pointers of the same type in the same statement - which leads on to the next
-  rule:
-* When declaring multiple pointers, never do so in a single statement, e.g.
-  `SomeObject* p1, *p2;` - instead, always split them out onto separate lines
-  and write the type name again, to make it quite clear what's going on, and
-  avoid the danger of missing out any vital asterisks.
-* The previous point also applies to references, so always put the `&` next to
-  the type rather than the variable, e.g. `void foo (Thing const& thing)`. And
-  don't put a space on both sides of the `*` or `&` - always put a space after
-  it, but never before it.
-* The word `const` should be placed to the right of the thing that it modifies,
-  for consistency. For example `int const` refers to an int which is const.
-  `int const*` is a pointer to an int which is const. `int *const` is a const
-  pointer to an int.
-* Always place a space in between the template angle brackets and the type
-  name. Template code is already hard enough to read!
-
-## Naming conventions
-
-* Member variables and method names are written with camel-case, and never
-  begin with a capital letter.
-* Class names are also written in camel-case, but always begin with a capital
-  letter.
-* For global variables... well, you shouldn't have any, so it doesn't matter.
-* Class data members begin with `m_`, static data members begin with `s_`.
-  Global variables begin with `g_`. This is so the scope of the corresponding
-  declaration can be easily determined.
-* Avoid underscores in your names, especially leading or trailing underscores.
-  In particular, leading underscores should be avoided, as these are often used
-  in standard library code, so to use them in your own code looks quite jarring.
-* If you really have to write a macro for some reason, then make it all caps,
-  with underscores to separate the words. And obviously make sure that its name
-  is unlikely to clash with symbols used in other libraries or 3rd party code.
-
-## Types, const-correctness
-
-* If a method can (and should!) be const, make it const!
-* If a method definitely doesn't throw an exception (be careful!), mark it as
-  `noexcept`
-* When returning a temporary object, e.g. a String, the returned object should
-  be non-const, so that if the class has a C++11 move operator, it can be used.
-* If a local variable can be const, then make it const!
-* Remember that pointers can be const as well as primitives; For example, if
-  you have a `char*` whose contents are going to be altered, you may still be
-  able to make the pointer itself const, e.g. `char* const foobar = getFoobar();`.
-* Do not declare all your local variables at the top of a function or method
-  (i.e. in the old-fashioned C-style). Declare them at the last possible moment,
-  and give them as small a scope as possible.
-* Object parameters should be passed as `const&` wherever possible. Only
-  pass a parameter as a copy-by-value object if you really need to mutate
-  a local copy inside the method, and if making a local copy inside the method
-  would be difficult.
-* Use portable `for()` loop variable scoping (i.e. do not have multiple for
-  loops in the same scope that each re-declare the same variable name, as
-  this fails on older compilers)
-* When you're testing a pointer to see if it's null, never write
-  `if (myPointer)`. Always avoid that implicit cast-to-bool by writing it more
-  fully: `if (myPointer != nullptr)`. And likewise, never ever write
-  `if (! myPointer)`, instead always write `if (myPointer == nullptr)`.
-  It is more readable that way.
-* Avoid C-style casts except when converting between primitive numeric types.
-  Some people would say "avoid C-style casts altogether", but `static_cast` is
-  a bit unreadable when you just want to cast an `int` to a `float`. But
-  whenever a pointer is involved, or a non-primitive object, always use
-  `static_cast`. And when you're reinterpreting data, always use
-  `reinterpret_cast`.
-* Until C++ gets a universal 64-bit primitive type (part of the C++11
-  standard), it's best to stick to the `std::int64_t` and `std::uint64_t` typedefs.
-
-## Object lifetime and ownership
-
-* Absolutely do NOT use `delete`, `deleteAndZero`, etc. There are very very few
-  situations where you can't use a `ScopedPointer` or some other automatic
-  lifetime management class.
-* Do not use `new` unless there's no alternative. Whenever you type `new`, always
-  treat it as a failure to find a better solution. If a local variable can be
-  allocated on the stack rather than the heap, then always do so.
-* Do not ever use `new` or `malloc` to allocate a C++ array. Always use a
-  `HeapBlock` instead.
-* And just to make it doubly clear: Never use `malloc` or `calloc`.
-* If a parent object needs to create and own some kind of child object, always
-  use composition as your first choice. If that's not possible (e.g. if the
-  child needs a pointer to the parent for its constructor), then use a
-  `ScopedPointer`.
-* If possible, pass an object as a reference rather than a pointer. If possible,
-  make it a `const` reference.
-* Obviously avoid static and global values. Sometimes there's no alternative,
-  but if there is an alternative, then use it, no matter how much effort it
-  involves.
-* If allocating a local POD structure (e.g. an operating-system structure in
-  native code), and you need to initialise it with zeros, use the `= { 0 };`
-  syntax as your first choice for doing this. If for some reason that's not
-  appropriate, use the `zerostruct()` function, or in case that isn't suitable,
-  use `zeromem()`. Don't use `memset()`.
-
-## Classes
-
-* Declare a class's public section first, and put its constructors and
-  destructor first. Any protected items come next, and then private ones.
-* Use the most restrictive access-specifier possible for each member. Prefer
-  `private` over `protected`, and `protected` over `public`. Don't expose
-  things unnecessarily.
-* Preferred positioning for any inherited classes is to put them to the right
-  of the class name, vertically aligned, e.g.:
-        class Thing  : public Foo, 
-                       private Bar
-        {
-        }
-* Put a class's member variables (which should almost always be private, of course),
-  after all the public and protected method declarations.
-* Any private methods can go towards the end of the class, after the member
-  variables.
-* If your class does not have copy-by-value semantics, derive the class from
-  `Uncopyable`.
-* If your class is likely to be leaked, then derive your class from
-  `LeakChecked<>`.
-* Constructors that take a single parameter should be default be marked
-  `explicit`. Obviously there are cases where you do want implicit conversion,
-  but always think about it carefully before writing a non-explicit constructor.
-* Do not use `NULL`, `null`, or 0 for a null-pointer. And especially never use
-  '0L', which is particulary burdensome. Use `nullptr` instead - this is the
-  C++2011 standard, so get used to it. There's a fallback definition for `nullptr`
-  in Beast, so it's always possible to use it even if your compiler isn't yet
-  C++2011 compliant.
-* All the C++ 'guru' books and articles are full of excellent and detailed advice
-  on when it's best to use inheritance vs composition. If you're not already
-  familiar with the received wisdom in these matters, then do some reading!
-
-## Miscellaneous
-
-* Constrain the scope of identifiers to the smallest area that needs it. Consider
-  using nested classes or classes inside functions, if doing so will expose less
-  interface and implementation overall.
-* `goto` statements should not be used at all, even if the alternative is
-  more verbose code. The only exception is when implementing an algorithm in
-  a function as a state machine.
-* Don't use macros! OK, obviously there are many situations where they're the
-  right tool for the job, but treat them as a last resort. Certainly don't ever
-  use a macro just to hold a constant value or to perform any kind of function
-  that could have been done as a real inline function. And it goes without saying
-  that you should give them names which aren't going to clash with other code.
-  And `#undef` them after you've used them, if possible.
-* When using the `++` or `--` operators, never use post-increment if
-  pre-increment could be used instead. Although it doesn't matter for
-  primitive types, it's good practice to pre-increment since this can be
-  much more efficient for more complex objects. In particular, if you're
-  writing a for loop, always use pre-increment,
-  e.g. `for (int = 0; i < 10; ++i)`
-* Never put an "else" statement after a "return"! This is well-explained in the
-  LLVM coding standards...and a couple of other very good pieces of advice from
-  the LLVM standards are in there as well.
-* When getting a possibly-null pointer and using it only if it's non-null, limit
-  the scope of the pointer as much as possible - e.g. Do NOT do this:
-
-        Foo* f = getFoo ();
-        if (f != nullptr)
-            f->doSomething ();
-        // other code
-        f->doSomething ();  // oops! f may be null!
-
-  ..instead, prefer to write it like this, which reduces the scope of the
-  pointer, making it impossible to write code that accidentally uses a null
-  pointer:
-
-        if (Foo* f = getFoo ())
-            f->doSomethingElse ();
-
-        // f is out-of-scope here, so impossible to use it if it's null
-
-  (This also results in smaller, cleaner code)
