New operators MOD and DIV
SELECT ... FROM DUAL
TRUE = 1 and FALSE = 0

resulting code cleanup in our main loop.

onversion with check

fixed some possible bugs

fixed subselect error handling bug
fixed subselect UNION ALL bug
fixed thd->lex.select restoring
explain UNION subselect bug

Warning handling and initial prepared statement handling (last not complete yet)
Changed a lot of functions that returned 0/1 to my_bool type.
GRANT handling now uses read/write locks instead of mutex
Change basic net functions to use THD instead of NET
(needed for 4.1 protocol)
Use my_sprintf instead of sprintf() + strlen()
Added alloc_query() to be able to chare query initialization code with
prepared statements.
Cleanup handling of SHOW COUNT(*) WARNINGS and SELECT LAST_INSERT_ID()

Note that the following test fails (will be fixed ASAP):
sub_select, union, rpl_rotate_logs and rpl_mystery22

Fixed that GRANT ... REQUIRE options are not forgot when doing new GRANT
Changed fn_ext to point at first '.' after directory.
FLUSH LOGS removed numerical extension for all future update logs.
Fixed the mysqld --help reports right values for --datadir and --bind-address
--log-binary=a.b.c now properly strips of .b.c
Fix that one can DROP UDF functions that was not loaded at startup
Made AND optional in REQUIRE
Added REQUIRE NONE

new error handling
Item_ref bug fixed

Made a some new buffers thread specific and changeable.
Resize of key_buffer.
AUTO_COMMIT -> AUTOCOMMIT
Fixed mutex bug in DROP DATABASE
Fixed bug when using auto_increment as second part of a key where first part could include NULL.
Split handler->extra() to extra() and extra_opt() to be able to support thread specific buffers.
Don't write message to error log when slave reconnects becasue of timeout.
Fixed possible update problem when using DELETE/UPDATE on small tables
(In some cases we used index even if table scanning would be better)
A lot of minior code cleanups

fixed bug in sum function in subselect

Remove dupicated code

Added missing checking of no_keyread

Still not able to make a proper test case as this crashes on files 
where key and data pointers are 4 bytes each. Possibly a proper 
test case would require myisampack.

(All commit emails since 4.0.1 checked)
This had to be done now, before the 4.1 tree changes to much, to make it easy to propagate bug fixes to the 4.1 tree.

memory corruption I can only repeat on one system.

 slave start io_thread 
 slave start sql_thread
same for stop

Fixed memory leak on shutdown (Affects the embedded version & MyODBC)

Cleanup typos (like SKIPP -> SKIP)

Fix for using quoted table names with the SJIS character set.

Safer, a bit faster filesort.
Code changes to avoid calls to current_thd() (faster code).
Removed all compiler warnings from readline.

Manual Changelog update

Fixed problem with LIKE with latin1_de
Added parsing support of UNSIGNED LONG LONG
