675cbb72a6 Fix underflow issue for XRP:
When specifying that a result should be rounded up,
the code rounded up to a value suitable for a non-xrp
amount. When called with an xrp amount, if that rounded-up
value was less than one drop, the code rounded down to zero.

This could cause funded offers to be removed as unfunded.

e78b8e4cf3 mulDiv returns 0 if numerator is 0 and denominator isn't:
* Otherwise overflow checks result in divide by 0.
* If denominator is 0, let the divide by 0 exception throw.
* Move mulDiv out of STAmount

999701e384 Fix underflow rounding issue:
Very small payment could fail when STAmount::mulRound underflowed
and returned zero, when it should have rounded up to the smallest
representable value.

9329aafe53 Transaction queue and fee escalation (RIPD-598):
The first few transactions are added to the open ledger at
the base fee (ie. 10 drops).  Once enough transactions are
added, the required fee will jump dramatically. If additional
transactions are added, the fee will grow exponentially.

Transactions that don't have a high enough fee to be applied to
the ledger are added to the queue in order from highest fee to
lowest. Whenever a new ledger is accepted as validated, transactions
are first applied from the queue to the open ledger in fee order
until either all transactions are applied or the fee again jumps
too high for the remaining transactions.

Current implementation is restricted to one transaction in the
queue per account. Some groundwork has been laid to expand in
the future.

Note that this fee logic escalates independently of the load-based
fee logic (ie. LoadFeeTrack). Submitted transactions must meet
the load fee to be considered for the queue, and must meet both
fees to be put into open ledger.

59431c513a Add IOUAmount and XRPAmount (RIPD-976):
These numeric types replace the monolithic functionality
found in STAmount. They are not used yet.

6f5d8bba2d Reduce STAmount public interface (RIPD-867):
* Implement subtraction as addition to the additive inverse
* Do not allow comparison with, addition to or subtraction from integers
* Remove unused functions
* Convert member functions to free functions
* Isolate unit-test specific code into the unit test

5a7fa8cfa9 Reduce STAmount public interface (RIPD-867):
The STAmount class includes a number of functions which serve as thin
wrappers, which are unused or used only in one place, or which break
encapsulation by exposing internal implemenation details. Removing
such functions simplifies the interface of the class and ensures
consistency.

* getSNValue and getNValue are now free functions
* canonicalizeRound is no longer exposed
* Removed addRound and subRound
* Removed overloads of multiply, mulRound, divide and divRound

100a76f0e8 Remove nested types SField::ref and SField::ptr...
* This silences a warning about a redundant cv-qualifier.
* This makes future coding mistakes about redundant
  cv-qualifiers much less likely.
* This makes the code easier to read.

99c2fac143 STVar: optimized storage for STObject (RIPD-825):
This introduces the STVar container, capable of holding any STBase-derived
class and implementing a "small string" optimization. STObject is changed
to store std::vector<STVar> instead of boost::ptr_vector<STBase>. This
eliminates a significant number of needless dynamic memory allocations and
deallocations during transaction processing when ledger entries are
deserialized. It comes at the expense of larger overall storage requirements
for STObject.

df54b47cd0 Tidy up includes and add modules to the classic build:
An alternative to the unity build, the classic build compiles each
translation unit individually. This adds more modules to the classic build:

* Remove unity header app.h
* Add missing includes as needed
* Remove obsolete NodeStore backend code
* Add app/, core/, crypto/, json/, net/, overlay/, peerfinder/ to classic build

60f27178b8 Levelization, improve structure of source files:
Source files are moved between modules, includes changed and added,
and some code rewritten, with the goal of reducing cross-module dependencies
and eliminating cycles in the dependency graph of classes.

* Remove RippleAddress dependency in CKey_test
* ByteOrder.h, Blob.h, and strHex.h are moved to basics/. This makes
  the basics/ module fully independent of other ripple sources.
* types/ is merged into protocol/. The protocol module now contains
  all primitive types specific to the Ripple protocol.
* Move ErrorCodes to protocol/
* Move base_uint to basics/
* Move Base58 to crypto/
* Remove dependence on Serializer in GenerateDeterministicKey
* Eliminate unity header json.h
* Remove obsolete unity headers
* Remove unnecessary includes

4a49fefdd9 Various cleanups:
* Replace SYSTEM_NAME and other macros with C++ constructs
* Remove RIPPLE_ARRAYSIZE and use std::extent or ranged for loops
* Remove old-style, unused offer crossing unit test
* Make STAmount::saFromRate free and remove default argument

f9aa3e0da5 Add more unit tests to rpc/impl/TransactionSign (RIPD-480):
By adding a mock it is possible to test the transactionSign
function without interacting with the ledger.  This is the
smallest change I could come up with that allows transactionSign
to be unit tested.

The unit tests are white boxed.  Each test case is a result
of examining the code and identifying behavior associated with
different JSON fields.  That means the tests are not based on
requirements, they are based on observed behavior.
