[tarantool-patches] [PATCH] sql: remove ENGINE from list of reserved keywords

[Nikita Pettik <korablev@tarantool.org>]

ENGINE became reserved keyword in 1013a744b. There's no any actual
reason why ENGINE should be reserved keyword. What is more, we are going
to use this word as a name of some fields for tables forming
informational schema. Hence, until it is too late (it is not documented
yet), let's remove ENGINE from the list of reserved keywords and allow
identifiers be that word.
