Backport of patch for Bug#34604 (from 6.0)

post push fix for bug#20129, test failed due to non existing
source files.

mysql-test/Makefile.am:
  Bug#20129: ALTER TABLE ... REPAIR PARTITION ... complains that
  partition is corrupt
  
  Test parts.partition_repair_myisam failed because the corrupted
  pre fabricated files was not included in the dist-file.
mysql-test/suite/parts/r/partition_special_innodb.result:
  Bug#34604: hander::ha_rnd_end(): Assertion inited==RND failed
  
  updated result file
mysql-test/suite/parts/t/partition_special_innodb-master.opt:
  Bug#34604: hander::ha_rnd_end(): Assertion inited==RND failed
  
  Added parameter to speed up the test.
  Set to 2 seconds to be working on slow machines.
mysql-test/suite/parts/t/partition_special_innodb.test:
  Bug#34604: hander::ha_rnd_end(): Assertion inited==RND failed
  
  Added test for verifying the bug (without the patch in
  ha_partition.cc, this crashes a debug compiled server)
sql/ha_partition.cc:
  Bug#34604: hander::ha_rnd_end(): Assertion inited==RND failed
  
  In some cases error was not properly propagated through
  ha_partition::rnd_next.
  
  Will now return the error code from the partitions rnd_next and
  update m_part_spec.start_part and m_last_part properly.
  This makes the inited state to be correct.
