[tarantool-patches] [PATCH 2/8] port: move struct port_sql to box/port.h

[Nikita Pettik <korablev@tarantool.org>]

We are going to use port_sql_create() in box/lua/execute.c so to be able
to call it let's make port_sql_create() non-static and move its
declaration to box/port.h alongside with struct port_sql (since
box/port.h already contains struct port_tuple and struct port_lua).

No functional changes are provided.

Needed for #3292
