* Don't fail the build on unused parameters gRPC headers have unused parameters so this breaks the test build. * Pull in updated compiler files from gRPC There have been some API breaks in gRPC lately. This commit pulls in the most recent version of the files in this repo that are just copied from gRPC. * Modify the gRPC files so that they can work with Flatbuffers The files taken from gRPC do not work out-of-the-box with Flatbuffers. This commit modifies them so that they work. Hopefully this commit will be able to serve as a guide or maybe even be cherry-picked on top of new versions of those files as newer versions from gRPC are pulled in. * Adjust the rest of Flatbuffers to work with the new gRPC * Change idl_gen_grpc.cpp to work with the new API * Add missing #include in flatbuffers/grpc.h * Run tests/generate_code.sh and check in the results * Don't link with grpc++_unsecure and (secure) grpc. That's just weird * Revert unrelated JS/TS test changes * Simplify compiler/config.h There is no need to import this file from gRPC. In fact, it probably makes sense to not do so, since it seems to be intended to have project specific configuration in it. * Don't emit C++ types in the Go gRPC code generator * Don't emit C++ #includes in generated gRPC code Before this PR, there was a Go-specific additional_includes method in schema_interface.h, which is shared with the gRPC repo. The additional parameter to FlatBufFile in idl_gen_grpc.cpp makes that unnecessary, which means we need less Flatbuffer-specific changes in gRPC.
