Improve binapi generator

- simplified Size/Marshal/Unmarshal methods
- replace struc in unions with custom marshal/unmarshal
- fix imports in generated files
- fix mock adapter
- generate rpc service using low-level stream API (dumps generate control ping or stream msg..)
- move examples/binapi to binapi and generate all API for latest release
- add binapigen.Plugin for developing custom generator plugins
- optionally generate HTTP handlers (REST API) for RPC services
- add govpp program for browsing VPP API
