.deb packaging fixes: make mariadb-common a real package, which depends on

mysql-common and places mariadb-specific stuff in /etc/mysql/conf.d/mariadb.cnf.
This should allow to co-exist with default Debian mysql-common package and
help resolve dependencies when installing mariadb among multiple available
versions of MySQL from different repositories.

-# 2009-10-07

-# This is *not* an optimised config, merely a more sane baseline:
-# - InnoDB default (e.g., ACID out-of-the-box, same as on Windows)
-# - strict mode (for proper input checks, same as on Windows)
-# - various other useful settings
-# - make use of MariaDB/Percona/OurDelta enhancements/extensions
-#
-# For tuning assistance, please see http://openquery.com/services
-# =================================================================

 # You can copy this file to one of:
 # - "/etc/mysql/my.cnf" to set global options,
 # - "~/.my.cnf" to set user-specific options.
