jessie ships mysql-5.5 and mariadb-10.0. Given that stretch no longer ships
mysql but only mariadb, we could just let mysql-5.5 go end of life, mark it as
unsupported (or drop the server part), and keep supporting mariadb-10.0. Users
will need to move to mariadb at some point anyway. The only problem is that
mariadb-10.0 goes EOL on March 2019. mariadb-10.1 is EOL on October 2020, so if
we decided to provide that in jessie that would be enough.

(Just giving some more options here.)
