* Remove all builds except cmake gcc & clang debug.
* Time some dependency and build operations, using a custom format to avoid
interfering with other timers.
* Use Travis's "trusty" infrastructure.
* Install more dependencies via apt.
* Update boost version to 1.65.1.
* Do not run unit tests under gdb - several security features prevent
it from running correctly.
* Run test job with two processes.
A bug in gdb is crashing when demangling some symbols. Gdb needs to be updated
to at least gdb 8.
Only run the debug build under gdb (other builds can time out).
* Simplify Travis APT config.
* Automatically retry Travis build and test script. Will result in fewer
false negatives.
* Travis install scripts use absolute paths.
* Build a library of cmake functions for reuse.
* Disallow cmake builds in project root.
* Disallow cmake default 32-bit Visual Studio builds.
* Add several missing nonunity / header files, including all unit tests to
cmake.
* Change gcc.debug.nounity Travis build to use cmake, instead of adding
builds.
* Change Appveyor build to cmake. Eliminates most spurious failures, which
are caused by python or scons failing to download.
* SConstruct will set ABI based on ubuntu flavor
* Script to bring in packages for various ubuntu flavors
* Script to bring in packages for various fedora 22
* Remove unneeded environment variable from travis
* Script to build boost with correct API flags
* `--static` flag to control static linking
* Remove cxx14 compatibility layer from ripple
* Update travis to clang 3.6 and drop gcc 4.8
* Remove unneeded beast CXX14 defines
* Do not run clang build with gdb with travis
* Update circle ci to clang 3.6 & gcc-5
* Don't run rippled in gdb, clang builds crash gdb
* Staticly link libstdc++, boost, ssl, & protobuf
* Support builds on ubuntu 15.10
