Manually importing Ingo's fix for BUG#22119 

"Changing MI_KEY_BLOCK_LENGTH makes a wrong myisamchk"
in the Maria tree as it is really needed to get "ma_test_all" to pass
(this bug showed up in Maria first, not in MyISAM).
Now ma_test_all does not have corruption messages about test2 anymore,
and shows the same output as mi_test_all except that
ma_test_all has this at the start:
lt-maria_chk: MARIA file test1
lt-maria_chk: warning: Size of indexfile is: 8192          Should be: 16384
MARIA-table 'test1' is usable but should be fixed
This was already true before importing the bugfix.
Wonder if normal.
NOTE: this bugfix is currently in 5.1-engines, in a few days
will be in the main 5.1, then we'll merge 5.1
into Maria: this will merge the bugfix into storage/myisam, but there
will be no need to apply it to storage/maria again. I just couldn't
wait a few days for the 5.1-engines->5.1 merge to be allowed.
