Bug#35161: --myisam-recover does not work for partitioned MyISAM tables

Problem was that auto_repair, is_crashed and check_and_repair was not
implemented in ha_partition.

Solution, implemented them as loop over all partitions for is_crashed and
check_and_repair, and using the first partition for auto_repair.

(Recommit after fixing review comments)
