Proposal: Hybrid programming with lua-resty-ffi

[kingluo]

lua-resty-ffi provides an efficient and generic API to do hybrid programming in openresty with mainstream languages (Go, Python, Java, Rust, Node.js, etc.).

Features:

• nonblocking, in coroutine way
• simple but extensible interface, supports any C ABI compliant language
• once and for all, no need to write C/Lua codes to do coupling anymore
• high performance, faster than unix domain socket way
• generic loader library for python/java
• any serialization message format you like

I hope I could merge this library into openresty. It's meaningful to extend the ecosystem of openresty. Thanks. @agentzh @zhuizhuhaomeng
