27d978b891 Simplify SHAMapItem construction:
The existing class offered several constructors which were mostly
unnecessary. This commit eliminates all existing constructors and
introduces a single new one, taking a `Slice`.

The internal buffer is switched from `std::vector` to `Buffer` to
save a minimum of 8 bytes (plus the buffer slack that is inherent
in `std::vector`) per SHAMapItem instance.

f072469409 Simplify & modernize code:
- Simplify and consolidate code for parsing hex input.
- Replace beast::endian::order with boost::endian::order.
- Simplify CountedObject code.
- Remove pre-C++17 workarounds in favor of C++17 based solutions.
- Improve `base_uint` and simplify its hex-parsing interface by
  consolidating the `SexHex` and `SetHexExact` methods into one
  API: `parseHex` which forces callers to verify the result of
  the operation; as a result some public-facing API endpoints
  may now return errors when passed values that were previously
  accepted.
- Remove the simple fallback implementations of SHA2 and RIPEMD
  introduced to reduce our dependency on OpenSSL. The code is
  slow and rarely, if ever, exercised and we rely on OpenSSL
  functionality for Boost.ASIO as well.

dbee3f01b7 Clean up and modernize code:
This commit removes obsolete comments, dead or no longer useful
code, and workarounds for several issues that were present in older
compilers that we no longer support.

Specifically:

- It improves the transaction metadata handling class, simplifying
  its use and making it less error-prone.
- It reduces the footprint of the Serializer class by consolidating
  code and leveraging templates.
- It cleanups the ST* class hierarchy, removing dead code, improving
  and consolidating code to reduce complexity and code duplication.
- It shores up the handling of currency codes and the conversation
  between 160-bit currency codes and their string representation.
- It migrates beast::secure_erase to the ripple namespace and uses
  a call to OpenSSL_cleanse instead of the custom implementation.

63503ee8f0 Improve platform detection and reduce includes:
The existing platform detection code was derived from the old Beast
library, which was, itself, derived from JUCE.

This commit removes that code and replaces it with the Boost.Predef
library which defines a consistent set of compiler, architecture,
operating system, library, and other version numbers.

For more on Boost.Predef, please see the Boost documentation. The
documentation for the current version as of this writing is at:
https://www.boost.org/doc/libs/1_71_0/doc/html/predef.html

773dcd1d48 Modernize base_uint:
*  Add construction and assignment from a generic
   contiguous container.  Both compile-time and run time
   safety checks are made to ensure the safety of this
   conversion.

*  Remove base_uint::copyFrom.  The generic copy assignment
   operator now does this functionality with enhanced
   safety and better syntax.

*  Remove construction from and dedendence on Blob.
   The generic constructor and assignment now handle this
   functionality.

*  Fix client code to adhere to this new API.

*  Removed the use of fromVoid in PeerImp.cpp as it was
   an inappropriate use of this dangerous API.  The
   generic container constructors do it with enhanced
   safety and better syntax.

*  Rename data member pn to data_ and make it private.

*  Remove constraint from hash_append

*  Remove array_type alias

710f9ee1ac Relax overly-strict assert in Serializer constructor (RIPD-1701):
The constructor would previously assert that the specified buffer pointer
was non-null, even if the buffer size is specified as 0. While reasonable,
this also makes it more difficult to use this API.

ad5c5f1969 STObject::applyTemplate() throws with description of error:
The `STObject` member function `setType()` has been renamed to
applyTemplate() and modified to throw if there is a template
mismatch.

The error description in the exception is, in certain cases,
used, to better indicate why a particular transaction was
considered ill formed.

Fixes #2585.

c71eb45240 Eliminate potential undefined behavior (RIPD-1685):
Under certain conditions, we could call `memcpy` or `memcmp` with a null
source pointer. Even when specifying 0 as the amount of data to copy this
could result in undefined behavior under the C and C++ standards.

3974ddd8f7 Remove RippleAddress:
The RippleAddress class was used to represent a number of fundamentally
different types: account public keys, account secret keys, node public
keys, node secret keys, seeds and generators.

The class is replaced by the following types:
* PublicKey for account and node public keys
* SecretKey for account and node private keys
* Generator for generating secp256k1 accounts
* Seed for account, node and generator seeds

d468deee12 Refactor Ledger and LedgerEntrySet:
Member functions and free functions on Ledger and LedgerEntrySet are
rewritten in terms of new abstract interfaces `BasicView` and `View`,
representing the set of non-decomposable primitives necessary to read
and write state map items in a ledger, and to overlay a discardable
view onto a Ledger that can calculate metadata during transaction
processing. const-correctness is enforced through the parameter and
return types.

The MetaView now supports multi-level stacking: A MetaView can be
stacked on top of either a Ledger or another MetaView, up to any
number of levels.

The getSLEi member function is removed. The CachedView wrapper
replaces it, wrapping a View such that any function called with a
CachedView will go through the SLECache.

* Add BasicView, View, CachedView
* Rename LedgerEntrySet to MetaView
* Factor out free functions
* Consolidate free functions in ViewAPI
* Remove unused class members and free functions

c25184cc88 Add sha512Half and SHA512HashHasher:

a2acffdfa3 New serialized object, public key, and private key interfaces
This introduces functions get and set, and a family of specialized
structs called STExchange. These interfaces allow efficient and
seamless interchange between serialized object fields and user
defined types, especially variable length objects.

A new base class template TypedField is mixed into existing SField
declarations to encode information on the field, allowing template
metaprograms to both customize interchange based on the type and
detect misuse at compile-time.

New types AnyPublicKey and AnySecretKey are introduced. These are
intended to replace the corresponding functionality in the deprecated
class RippleAddress. Specializations of STExchange for these types
are provided to allow interchange. New free functions verify and sign
allow signature verification and signature generation for serialized
objects.

* Add Buffer and Slice primitives
* Add TypedField and modify some SField
* Add STExchange and specializations for STBlob and STInteger
* Improve STBlob and STInteger to support STExchange
* Expose raw data in RippleAddress and Serializer

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
