84e7c9633a Fix error in prefix compression of keys in MyISAM when key length changed from 254 -> 255 
Bug #17705 "FT Index corruption occurs with UTF8 data..."
(Actually, the bug had nothing to do with FT index but with general key compression)

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).

297d80dc11 BUG#11336 - fulltext index corruption after repair_by_sort and mi_delete 
for uca collation isalnum and strnncollsp don't agree on whether
0xC2A0 is a space (strnncollsp is right, isalnum is wrong).

they still don't, the bug was fixed by avoiding strnncollsp

58c64aea92 memcpy_overlap() removed, as 
1. it's wrong to use memcpy() for overlapped areas;
  2. we use it only once.
During merge to 4.1 will remove a memcpy_overlap() call 
from strings/ctype-tis620.c as well in order to fix 
bug #10836: ctype_tis620 test failure with ICC-compiled binaries on IA64.

4025d2965b Bug#9112 - Merge table with composite index producing invalid results with some queries 
The problem was an ab-use of last_rkey_length.
Formerly we saved the packed key length (of the search key)
in this element. But in certain cases it got replaced by 
the (packed) result key length.
Now we use a new element of MI_INFO to save the packed key 
length of the search key.
