Lawrence Chan da67c0a71f [C++] Improve flatbuffers + gRPC integration (#4310)
* Rework flatbuffers + gRPC integration

- Introduce `flatbuffers::grpc::Message<T>`, a `grpc_slice`-backed
message buffer that handles refcounting and allows flatbuffers to
transfer ownership to gRPC efficiently. This replaces
`flatbuffers::BufferRef<T>`, which required a copy call and was also
unsafe w.r.t. buffer lifetime.
- Introduce `flatbuffers::grpc::MessageBuilder`, a gRPC-specific builder
that forces a `grpc_slice`-backed allocator and also adds some helpful
`Message<T>`-related methods.
- Update serializers accordingly (now zero-copy between flatbuffers and
gRPC).

* gRPC: verify messages by default, but allow user to override

* gRPC: fix some formatting issues

* Disable verification by default, but add helper method

* Make FlatBufferBuilder fields protected + remove vec accessor

* Use bool add_ref parameter to toggle refcount incr

* Remove unnecessary inline specifiers

* Fix formatting

* Use auto

* Remove empty lines

* Use grpc_slice helper macros

* Simplify reset code

* Disable Message copy ctor and assignment by default

* Remove unused member

* Enable gRPC verification by default

* Use auto

* Bake in message verification (remove template specialization)

* Add RoundUp func

* Consolidate gRPC message copy flag

* Make vector_downward allocations fully lazy

* Test message verification failure code/message

* Add grpctest verification test comments

* Simplify reallocate implementation

* Make initial_size a size_t

* Use ternary op for growth_policy

* Use truthiness rather than dont explicit nullptr check

* Indent preprocessor directives

* Remove grpc message copy/assignment

* Fix a few bugs

* Add gRPC example

* Add basic gRPC docs

* Use doxygen EXAMPLE_PATH + @include

* Reference example fbs in grpc docs

* Move gRPC examples into grpc/samples

* Fix pointer/reference formatting

* Use std::function rather than templated callback func

* Create fresh message builder for each request

* Use Clear() in Reset() impl

* Use FLATBUFFERS_CONSTEXPR

Per Grön 9aeeddf5ac C++/Go: Update gRPC related code to work with gRPC 1.3+ (#4305)
* 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.
