[Tarantool-patches] [PATCH 0/3] box_return_mp

[Vladislav Shpilevoy]

The patchset extends the public C API with a function
box_return_mp(). It allows to return arbitrary MessagePack from
user's code.

First patch is not really related to the ticket, but related to
struct port, which is touched here.

Second patch introduces a new struct port - port_c. It replaces
port_tuple for stored C functions, and is able to store both
tuples and raw MessagePack.

Third patch introduces the new public function.
