Incorrect "key size exceeds implementation restriction for index" error

* Bugfix CORE-1713
Distinct with blob fields
Contributor(s):
Dmitry Yemanov <dimitr at firebirdsql.org>
Note(s):
This change restores the legacy behavior of DISTINCT / UNION / GROUP BY and ORDER BY operations.
Please beware that they may produce incorrect result set, because the ordering / distinct
is performed using blob IDs instead of the blob contents.
It implies that changes CORE-859 and CORE-1530 are rolled back.

* Bugfix CORE-1694
Bug in create/alter database trigger (with Russian comment)
