* Add flatc '--cpp_std' switch and sandbox for C++17 code generator
- Added 'flac --cpp_std legacy' for compatibility with old compilers (VS2010);
- Added experimental switch 'flac --cpp_std c++17' for future development;
- Added C++17 sandbox test_cpp17.cpp;
- C++ code generator generates enums with explicit underlying type to avoid problems with the forward and backward schema compatibility;
- Adjusted CMakeLists.txt, CI and generate code scripts to support of introduced '--cpp_std';
* Fix --cpp_std values: c++0x, c++11, c++17
* Add 'cpp::CppStandard' enum
* Add testing engine into test_cpp17
* Rebase to upstream/master
* Set default '--cpp-std C++0x'
* Fix code generation (--cpp_std C++11) in CMakeLists.txt
- Fix dependency declaration of grpctest target
* Revert --cpp-std for the tests from explicit C++11 to flatc default value (C++0x)
* Efficient conversion of FlatBufferBuilder to grpc::MessageBuilder
* Added a variety of tests to validate correctness of the MessageBuilder move operations.
Disable MessageBuilder half-n-half tests on MacOS.
* Fix failing Android build
* Generalized the MessageBuilder move constructor to accept a deallocator
* Add FlatBufferBuilder move semantics tests to main
Do not eagerly delete/reset allocators in release and release_raw functions
Update android, vs2010 build files
New tests for various types of FlatBufferBuilders and move semantics
* Improve test failure output with function names
Unit tests
Update flatbuffers + gRPC build instructions
Update CMakeLists.txt with cmake variables for grpc and protobuf install paths
Update tests for travis build
