Bug#793316: transition: mysql-5.6

[Andreas Beckmann <anbe@debian.org>]

mysql-5.6 is now ready for migration to testing.
It needs to go in along with mariadb-10.0 while mysql-5.5 gets removed
at the same time. Could someone please add the appropriate hints?

That's for getting new versions into stretch and RC bugs out. Thereafter
the entanglement of the packages is to be reduced s.t. they can migrate
on their own again ...


Thanks

Andreas
