This patchset reworks Tarantool's functions machinery to support
persistent Lua functions and provide an universal way to call any
registered function.

This patchset consists of following conceptual changes:
1. Func updates on alter were simplified: now replace _func tuple is
   forbidden and func_new constructor may fail. This makes possible to
   define a failable function object constructors.
2. box_lua_call and box_lua_eval were refactored to do nottake call_request
   argument and to use input and output port instead. A new msgpack_port allows
   to use this abstraction also for a regular memory msgpack.
3. Introduced an abstract function class and func_c and func_lua
   implementations that allow to call C and Lua functions correspondingly
   with uniform API defined on base func class.
4. Introduced an infrastructure to call functions from Lua. A new box.func
   folder exports functions objects that have :call and :drop methods and their
   definition.
4. Introduced persistent Lua functions. Such functions are a part of Tarantool
   snapshoot so they are available even after restart. The new is_sandboxed
   option initializes a new persistent Lua function is a separate 'sandbox':
   an isolated environment with strong restrictions: only limited number of
   on-board functions are available, no global state is available at all.

Persistent Lua functions is an important step to implement functional indexes
in Tarantool. Only a deterministic, sandboxed, persistent Lua function may
be used as a functional index extractor.

Changes in version 4:
   Build of persistent Lua function in a sandbox
   New space format
   Minor review fixes

Changes in version 3:
   Source code is re-organised to be bit clear and to provide a better function
   object abstraction.
