Summary

This change adds an implementation of the IPC layer for FuzzerProxy. It translates calls to the FuzzerRemote* methods of the FuzzerRemoteInterface into messages sent over a fuzzer::ipc::Connection, and messages received over that connection into calls to the FuzzerProxy* methods.

This is change 18 of (at least) 20 for cross-process fuzzing support.

Multiprocess fuzzing will not be supported by the libFuzzer maintainers. Fuchsia has implemented a new approach with their Component Fuzzing Framework (RFC-117).
