  BUG#22937 - Valgrind failure in 'merge' test (ha_myisammrg.cc:329)
  
  This is addition to fix for bug21617. Valgrind reports an error when
  opening merge table that has underlying tables with less indexes than
  in a merge table itself.
  
  For each subtable check if number of keys is less than in merge table. Return
  an error and refuse to open merge table in this case.

  Copy at most min(file->keys, table->key_parts) elements from rec_per_key array.
  This fixes problems when merge table and subtables have different number of keys.
