moving out libmariadb as well. Otherwise the library would have a
dependency on the big mariadb package.

+# The MariaDB/MySQL tools read configuration files in the following order:

+# 2. "/etc/mysql/conf.d/*.cnf" to set global options.
+# 3. "~/.my.cnf" to set user-specific options.

+# If the same option is defined multiple times, the last one will apply.
