storage/maria/ma_range.c:
  old code, which is wrong now (key_len is now a local variable,
  not initialized). Fixes some problems in running ma_test2.
storage/maria/ma_test2.c:
  keypart_map should be used instead of length (fix of bad merge
  probably)
storage/maria/ma_test_recovery:
  less duplication in this script (one loop instead).
