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.

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.


sql/ha_myisammrg.cc:
  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.

Crash may happen when selecting from a merge table that has underlying
tables with less indexes than in a merge table itself.

If number of keys in merge table is not bigger than requested key number,
return error.

  underlying table.

Deletes on a big index could crash the index when it needs to
shrink.

Put a forgotten negation operator in.

No test case. It is too big for the test suite. And it does not
work with 4.0, only with higher versions. It is attached to the
bug report.


myisam/mi_delete.c:
  Bug#22384 - DELETE FROM table causes "Incorrect key file for table"
  Put a negation operator ('!') before _mi_get_last_key() in del().
  It returns NULL on error, non-NULL on success.

Any default value for a enum fields over UCS2 charsets was corrupted
