[Dovecot] [PATCH] Split sql drivers from lib-sql to plugins

Hi,

in order to solve rhbz#170960 [1], I split the sql drivers to plugins so that they are loaded dynamically and can be split to separate packages.

[1] https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=170960

The patches are here: [2] http://people.redhat.com/tjanouse/dovecot/145241/dovecot-1.0-split.patch [3] http://people.redhat.com/tjanouse/dovecot/145241/dovecot-trunk-split.patch (mv src/lib-sql/driver-mysql.c src/plugins/sql-mysql/, etc., afterwards)

I'd like to ask for your comments and whether it's ok for inclusion or at least ok to use in the Fedora package.

Regards,
