Desupported database drivers

Database drivers for old database client versions are removed according to the vendor de-support plans.

Database drivers desupported in versions 2.40:

PostgreSQL versions 8.0, 8.1 and 8.2 (dbmpgs80x, dbmpgs81x, dbmpgs82x).
Sybase Adaptive Server Anywhere (ASA) version 8 driver (dbmasa8x)
The dbmasa8x driver was provided for the Sybase ASA desktop database engine (renamed Sybase SQL Anywhere when writing these lines). Since version 2.30, Genero Business Development Language supports a new driver to connect to Sybase Adaptive Server Enterprise (ASE): dbmase*.
