* Track stats for ledger fetch and output
* Reduce entries queried on timeout
* Allow duplicate node requests on timeout
* Don't query deep on timeout
* Adjust latency tuning
* Change high latency cutoff
* Set absolute limit on reply entries
* Small optimizations
* Hold a shared_ptr<SHAMapItem const> instead of a shared_ptr<SHAMapItem>.
* Compiler helps us enforce data immutability.
* Make SHAMapAbstractNode::addRaw const

* This reduces the memory requirements of both leaf and inner nodes.
* The name SHAMapTreeNode is retained for leaf nodes so as to keep
the public API of SHAMap stable.
This changes TMGetLedger protocol in a backward-compatible way to include
a "query depth" parameter - the number of extra levels in the SHAMap tree
that a server should return in the corresponding TMLedgerData. Depending
on the value or absence of the field, a server may adjust the amount of
returned data based on the observed latency of the requestor: higher
latencies will return larger data sets (to compensate for greater
request/response turnaround times).
* Performance motivated.
* Several of these called size() which is O(N) in gcc-4.8.
* Remove container copy from LedgerConsensusImp::playbackProposals().
* Addresses RIPD-284.
When fetchNodeFromDB discovers a missing node in the database it
must reset the ledger sequence to 0. By treating this as a logically
const operation, even though not physically const, many other member
functions can be made const, including compare.
SHAMapTreeNode
* Remove SHAMapTreeNode::pointer and SHAMapTreeNode::ref.
* Add std includes necessary to make the header standalone.
* Remove implementation from the SHAMapTreeNode declaration.
* Make clear what part of SHAMapTreeNode is:
1) Truly public.
2) Used only by SHAMap.
3) Truly private to SHAMapTreeNode.
SHAMapItem
* Remove SHAMapItem::pointer and SHAMapItem::ref.
* Add std includes necessary to make the header standalone.
* Remove implementation from the SHAMapItem declaration.
* Make clear what part of SHAMapItem is:
1) Truly public.
2) Used only by SHAMapTreeNode.
3) Truly private to SHAMapItem.
SHAMapSyncFilter
* Add override for SHAMapSyncFilter-derived functions.
* Add missing header.
* Default the destructor and delete the SHAMapSyncFilter copy members.
SHAMapNodeID
* Remove unused mHash member.
* Remove unused std::hash and boost::hash specializations.
* Remove unused constructor.
* Remove unused comparison with uint256.
* Remove unused getNodeID (int depth, uint256 const& hash).
* Remove virtual specifier from getString().
* Fix operator<= and operator>=.
* Document what API is used outside of SHAMap.
* Move inline definitions outside of the class declaration.
SHAMapMissingNode
* Make SHAMapType a enum class to prevent unwanted conversions.
* Remove needless ~SHAMapMissingNode() declaration/definition.
* Add referenced std includes.
SHAMapAddNode
* Make SHAMapAddNode (int good, int bad, int duplicate) ctor private.
* Move all member function definitions out of the class declaration.
* Remove dependence on beast::lexicalCastThrow.
* Make getGood() const.
* Make get() const.
* Add #include <string>.
SHAMap
* Remove unused enum STATE_MAP_BUCKETS.
* Remove unused getCountedObjectName().
* Remove SHAMap::pointer
* Remove SHAMap::ref
* Remove unused fetchPackEntry_t.
* Remove inline member function definitions from class declaration.
* Remove unused getTrustedPath.
* Remove unused getPath.
* Remove unused visitLeavesInternal.
* Make SHAMapState an enum class.
* Explicitly delete SHAMap copy members.
* Reduce access to nested types as much as possible.
* Normalize member data names to one style.
* Change last of the typedefs to usings under shamap.
* Reorder some includes ripple-first, beast-second.
* Declare a few constructions from make_shared with auto.
* Mark those SHAMap member functions which can be, with const.
* Add missing includes
* 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
