These routines replace existing code to compute SHA512-Half hashes.
The new code accumulates serialized data into a hashing context
instead of allocating a buffer, for improved performance.
A few serialization changes coming from m-of-n development:
o Improve readability of SField.cpp.
o Better initialization of STObject.
o Trimming of STObject public methods.
o Add STObject::getFieldObject and STObject::setFieldObject.
o Make STObject::isEquivalent more robust.
o Improvements to whitespace, overrides, and virtuals.
This creates a new InboundTransactions object that handles transaction sets,
removing this responsibility from the consensus object. The main benefit is
that many inbound transaction operations no longer require the master lock.
Improve logic to decide which peers to query, when to add more peers, and
when to re-query existing peers.
* Remove unused members
* SerialIter holds only a pointer and offset now
* Use free functions for some Serializer members
* Use SerialIter in some places instead of Serializer
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
The SHAMap class is refactored into a separate module where each translation
unit compiles separate without errors. Dependencies on higher level business
logic are removed. SHAMap now depends only on basics, crypto, nodestore,
and protocol:
* Inject NodeStore::Database& to SHAMap
* Move sync filter instances to app/ledger/
* Move shamap to its own module
* Move FullBelowCache to shamap/
* Move private code to shamap/impl/
* Refactor SHAMap treatment of missing node handler
* Inject and use Journal for logging in SHAMap
