This has been deprecated and superceded by ezgrpc2 https://github.com/mnyoshie/ezgrpc2
Still in its draft.
requires: -lnghttp2 -lpthread -lz
- does not support over TLS.
- does not support streaming messages.
- only works on unix machine with poll.
Even though it's marketed as EZ, you'd have to deal with serialization

Requires further testing.
