Sergey Petrunya a86599e1e4 BUG#671340: Diverging results in with mrr_sort_keys=ON|OFF and join_cache_level=5 ...

- Make Mrr_ordered_index_reader() save the rowid across scan interruptions

Also
- Fix compiler warning for setup_buffer_sizes()
- Add commented key_copy/key_restore for better handling of a similar issue
  with index record being destroyed by scan interruption (which causes 
  incorrect evaluation of pushed index condition later on).
