[Tarantool-patches] [PATCH v4 0/6] box/func: implement cfunc Lua module

[Cyrill Gorcunov <gorcunov@gmail.com>]

The cfunc module provide a way to execute C stored procedures
on read only nodes without registring them in `_func` system space.

The series implements a bare minimum. There was a request to make
cfunc been Lua object with appropriate methods. If this is really
preferred then I'll implement this wrapping Lua code on top. I mean
that currently all operations are done via

 > require('cfunc').[create|drop|call|reload]

interface while there was a proposal to operate as

 > a = require('cfunc').create
 > a:call(args)

Please take a look once time permit.

v1-v3 are development ones and not sent.
