[tarantool-patches] [PATCH v2 0/7] Remove box.sql.execute

[imeevma@tarantool.org]

The goal of this patch-set is to make functions from execute.c
the only way to execute SQL statements. This goal includes
similar output for executed SQL statements no matter how they
were executed: through net.box or through box.

This is the second version of patch-set. It is not complete. It
still has no last part, which is replacing box.sql.execute by
box.execute, because it will lead to massive test editing.

The main goal of this version of patch-set is to try new design of
box.sql.execute() and decide to leave it as it is or modify it for
better performance.

General information of difference from previous version of
patch-set:
- Three patches from last version were moved to different branch.
- The order in which the patches were arranged was slightly
  changed.

A bit about patches of patch-set with comments about changes in
this version:

Patch 1 allows to use SQL query as plain text in sql_request.
Review fixes were made.

Patch 2 creates method for port which will allow us to dump port
directly to Lua stack. This was moved here from position 8.

Patch 3 makes function sql_response_dump() a bit more universal by
removing IPROTO functions from there. The main change from last
version is that xrow_decode_sql() was returned to execute.c.

Patch 4 allows us to design vstream by wrapping mpstream
functions. Nothing was changed for now.

Patch 5 creates interface vstream and its mpstream implementation.
Difference from previous version:
- vstream now is inherited from mpstream.
- vstream.c removed, msgpack implementation moved to mpstream.c
- Implementation of some methods were replaced by mpstream
  functions that were implicitly casted.
- encode_reply_* methods were removed. Their functionality is now
  performed by encode_enum() + encode_... + encode_map_commit().
- Flag is_flatted was moved to sql_response.

Patch 6 creates vstream implementation for Lua and defines new
box.sql.new_execute() function that will become box.execute() in
next vesions.
Difference from previous version:
- Added parameters binding for box.sql.new_execute().
- Lua implementation of vstream methods was moved to lua/sql.c.
- Changed the way errors was pushed to Lua stack.

Patch 10 is created to check that box.sql.new_execute() is able to
pass through tests created for box.sql.execute(). Almost nothing
changes from previous version.
