[Tarantool-patches] [PATCH v2 0/3] JSON preparation part 5

[Vladislav Shpilevoy]

The patchset is a fifth part of preparations to JSON updates of a tuple. It
reorganizes code. Before the path there was one huge file implementing xrow
update. Soon amount of the code will be much larger, and a new code structure
was needed to be able to maintain it. Now xrow update implementation consists of
several files. One file for general update functions and structures, one file
for top-level API used by other tarantool code, and one file per each
non-trivial type of xrow field update.

By the idea, each xrow_update_<type>.c will implement update of one of field
types such as array, bar, map, route. It allows to make these implementations
independent and easy to support.
