[debian-mysql] Bug#917088: Bug#917088: mariadb-server-10.3: #1071 - Specified key was too long; max key length is 1000 bytes

[Otto Kekäläinen]

The options innodb_file_format and innodb_large_prefix no longer exist
in 10.3, so they need to be removed.

Apparenlty we need something else to allow large keys again?
