[tarantool-patches] [PATCH 0/3] Concatenation operator type fixes

[Nikita Pettik <korablev@tarantool.org>]

This patch makes concatenation operator follow ANSI rules.
For now, only operands of string-like types (TEXT or BLOB) are
accepted. What is more, fixed resulting type of concatenation:
if both operands are of BLOB type, then the resulting value is of
BLOB value too.
