37cdb0fbf3 BUG#18036 - update of table joined to self reports table as crashed 
Certain updates of table joined to self results in unexpected
behavior.

The problem was that record cache was mistakenly enabled for
self-joined table updates. Normally record cache must be disabled
for such updates.

Fixed wrong condition in code that determines whether to use
record cache for self-joined table updates.

Only MyISAM tables were affected.

d0c6eb885d Bug#14980 - COUNT(*) incorrect on MyISAM table with certain INDEX 
For "count(*) while index_column = value" an index read
is done. It consists of an index scan and retrieval of
each key.

For efficiency reasons the index scan stores the key in
the special buffer 'lastkey2' once only. At the first 
iteration it notes this fact with the flag 
HA_STATE_RNEXT_SAME in 'info->update'.

For efficiency reasons, the key retrieval for blobs
does not allocate a new buffer, but uses 'lastkey2'...

Now I clear the HA_STATE_RNEXT_SAME flag whenever the 
buffer has been polluted. In this case, the index scan
copies the key value again (and sets the flag again).

1f3df2e669 Bug#14616 - Freshly imported table returns error 124 when using LIMIT 
Initialized usable_keys from table->keys_in_use instead of ~0
in test_if_skip_sort_order(). It was possible that a disabled
index was used for sorting.

3add511de7 Bug#9188 - Corruption Can't open file: 'table.MYI' (errno: 145) 
Since 4.1 keys are compared with trailing spaces. 
Thus, a "x " key can be inserted between a couple of "x" keys.
The existing code did not take this into account. Though the
comments in the code claimed it did.
