mariadb/mariadb-versioning-compat.patch

The issue is Fedora has changed ABI of MySQL client library downstream since
MySQL-5.5 (in order to prevent upstream's ABI mistakes), which started to make
problems for people building on one distro and running their software on other
distro. Detailed info and whole story RHBZ#1045013 [1].

With collaboration of MariaDB upstream, Oracle developer and Fedora we came up
with a solution, that we'll use both libmysqlclient_16 and libmysqlclient_18
versions for symbols, which were already in MySQL 5.1, while libmysqlclient_18
will be default one.

MariaDB/MySQL upstreams seem to be willing to use the same approach for RPM
packages they provide.
