Initial MariaDB support

We have decided to move away from MySQL and lib_mysqludf_preg since the udf is quite outdated and it appears that there is no "easy" way to revive the project.

This release contains a lot of bug fixes and the initial support for MariaDB without the lib_mysqludf_preg dependency (https://mariadb.com/kb/en/mariadb/pcre/).

MySQL specific functions will still be available but will stop being supported soon after.

special thanks to @ardichoke for the mariadb implementation
