- When a MyISAM table which belongs to a merge table union and is 
  renamed the associated file descriptors are closed on windows.
  This causes a server crash next time an insert or update is 
  performed on the merge table.
- This patch prevents the system from crashing on windows by
  checking for bad file descriptors every time the MyISAM table
  is locked by associated the merge table.

 - When an ALTER TABLE RENAME is performed on windows, the files are closed and their cached file 
   descriptors are marked invalid. Performing INSERT, UPDATE or SELECT on the associated merge
   table causes a server crash on windows. This patch adds a test for bad file descriptors when a 
   table attempts a lock. If a bad descriptor is found an error is thrown. An additional FLUSH TABLES
   will be necessary to further operate on the associated merge table.

Fix OPT_MYISAM_STATS_METHOD case, where the NULLS_EQUAL and NULLS_NOT_EQUAL methods were mixed up

In 5.0 we made LOAD DATA INFILE autocommit in all engines, while
only NDB wanted that. Users and trainers complained that it affected
InnoDB and was a change compared to 4.1 where only NDB autocommitted.
To revert to the behaviour of 4.1, we move the autocommit logic out of mysql_load() into
ha_ndbcluster::external_lock().
The result is that LOAD DATA INFILE commits all uncommitted changes
of NDB if this is an NDB table, its own changes if this is an NDB
table, but does not affect other engines.
Note: even though there is no "commit the full transaction at end"
anymore, LOAD DATA INFILE stays disabled in routines (re-entrency
problems per a comment of Pem).
Note: ha_ndbcluster::has_transactions() does not give reliable results
because it says "yes" even if transactions are disabled in this engine...

21913: DATE_FORMAT() Crashes mysql server if I use it through mysql-connector-j driver.

Variable character_set_results can legally be NULL (for "no conversion.")
This could result in a NULL deref that crashed the server.  Fixed.

(Although ran some additional precursory tests to see whether I could break
anything else, but no breakage so far.)
