- Better error from check_slave_param
- Better error message from TokuDB if it can't be compiled.
- Marked rpl_mixed_drop_create_temp_table and
  rpl_stm_drop_create_temp_table as big tests to stop timeout
  failures on power8
- Added sync_slave_with_master to semisync_future-7591 to
  ensure that slave is up to date with master before calling
  rpl_end.
- Disabled compiler warnings from connect and mroonga and on
  MacOSX.

Mroonga:
- Fixed bug when testing if file is a normal file that can be deleted
- Marked a lot of date and datetime test to not run on macosx.
  This is because mktime() can't handle negative years and this
  restricts mroonga so that it can only store dates after the year 1900.
