Version for 4.0.
It fixes two problems:
1. The cause of the bug was that we did not check the table version for
   the HANDLER ... READ commands. We did not notice when a table was
   replaced by a new one. This can happen during ALTER TABLE, REPAIR
   TABLE, and OPTIMIZE TABLE (there might be more cases). I call the fix
   for this problem "the primary bug fix".
2. mysql_ha_flush() was not always called with a locked LOCK_open.
   Though the function comment clearly said it must.
   I changed the code so that the locking is done when required. I call
   the fix for this problem "the secondary fix".

DISTINCT wasn't optimized away and caused creation of tmp table in wrong

Fix backported from 4.1. Now if optimizer founds that in result be only 1

When fixing Item_func_plus in ORDER BY clause field c is searched in all

mysql-test/r/merge.result:
  Bug#9112 - Merge table with composite index producing invalid results with some queries
  The new test result

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.

Enlarged the counter variables to ulonglong.

Solution for 4.0 and 4.1.
If the caller cannot re-open table(s), it gives a NULL
'refresh' argument to open_table(). We used to ignore
flushes then. Now we ignore drops too.
