Fix parseIniFile for duplicate sections
Remove unused ErrorReply function
Add Json::stream to write Value to a Streambuf
Add streambuf to_string function
Add PeerFinder onRedirects function
Remove obsolete sections from rippled-example.cfg:
* peer_port_proxy is obsolete since the MultiSocket was removed.
* peer_ssl_cipher_list has no effect, SSL ciphers are hard coded for security.
Remove obsolete websocket PROXY port
Remove obsolete multitls and proxy websocket features
Enable processor-specific optimizations when available:
The SConstruct is modified to enable processor specific optimizations on clang and gcc toolchains. This improves the performance of RocksDB's CRC function. It might also enable other used libraries that are in the codebase now or in the future to apply cpu-specific optimisations. The mtune option ensures that a binary compiled on one machine will function on another,
Avoid zero initialization of Blob:
This seemed to improve the performance of the copy, although there did seem to be some byte by byte copying still present. Further investigation recommended.
New class TempDirectory in UnitTestUtilities.
Delete temporary directories at the end of tests (RIPD-460).
Refactor Stoppable:
The Stoppable interface aids in the enforcement of invariants needed to
successful start and stop a multi-threaded application composed of classes
that depend on each other in complex ways.
* Test written to confirm the current behavior.
* Comments updated to reflect the current behavior.
* Public API reduced to what is currently in use.
* Protected data members made private.
* volatile bool members changed to std::atomic<bool>.
* std::atomic<int> members changed to std::atomic<bool>.
* Name storage uses std::string
Add repeatable NodeStore timing benchmark:
The timing test is changed to overcome possible file buffer cache effects by creating different read access patterns. The unittest-arg command line arguments allow running the benchmarks against any of the available backends and altering the parameters passed in the same format as rippled.cfg. The num_objects parameter permits variation of the number of key/values inserted. The data is random but matches reasonably well the values that rippled might generate.
Add new RocksDBQuickFactory for benchmarking:
This new factory is intended for benchmarking against the existing RocksDBFactory and has the following differences.
* Does not use BatchWriter
* Disables WAL for writes to memtable
* Uses a hash index in blocks
* Uses RocksDB OptimizeFor… functions
See Benchmarks.md for further discussion of some of the issues raised by investigation of RocksDB performance.
Improve nodestore benchmarking:
* Use more succinct while loops on NodeFactory.
* Better formatting of multiple test results.
* Updated benchmarks.
* Use simpler and faster RNG to generate test data.
Clean up Pathfinder.

* Restrict to 80-columns and other style cleanups.
* Make pathfinding a free function and hide the class Pathfinder.
* Split off unrelated utility functions into separate files.
Fix pathfinding with multiple issuers for one currency (RIPD-618).
In PathRequest, clear the LES sandbox before retrying pathfinding.
