database/adabase: Upgrade version 1.0 => 2.0 (SQLite Driver)

This new release provides some minor fixes for MySQL driver and brings
in the SQLite3 driver. The now has options where MySQL and SQLite drivers
are built by default, but either (but not both) can be disabled. The
adabase.gpr was changed to a template and moved into the codebase.
Also, since the adabase library can't be linked without the database
libraries, they've been added as library dependencies through the options
framework.
