Lots of code fixes to the replication code (especially the binary logging and index log file handling)
Fixed bugs in my last changeset that made MySQL hard to compile.
Added mutex around some data that could cause table cache corruptions when using OPTIMIZE TABLE / REPAIR TABLE or automatic repair of MyISAM tables.
Added mutex around some data in the slave start/stop code that could cause THD linked list corruptions
Extended my_chsize() to allow one to specify a filler character.
Extend vio_blocking to return the old state (This made some usage of this function much simpler)
Added testing for some functions that they caller have got the required mutexes before calling the function.
Use setrlimit() to ensure that we can write core file if one specifies --core-file.
Added --slave-compressed-protocol
Made 2 the minimum length for ft_min_word_len
Added variables foreign_key_checks & unique_checks.
Less logging from replication code (if not started with --log-warnings)
Changed that SHOW INNODB STATUS requre the SUPER privilege
More DBUG statements and a lot of new code comments

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

Fix wrong usage of constant which could cause mysqld to use index when doing an update/delete on small tables.
code cleanup

make some new mistakes.

delete.

(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.

Fixed slowdown problem on win98
Fixed syntax for ALTER TABLE .. RENAME

Test of unsigned BIGINT values
Fixes for queries-per-hour
Cleanup of replication code (comments and portability fixes)
Make most of the binary log code 4G clean
Changed syntax for GRANT ... QUERIES PER HOUR

Fixed bug in multi-table-delete

incorporations of the new stuff.

When Monty approves / corrects it, I will "port" it to multi-table
updates.

* multi-table updates
* new paid feature for limiting number of queries per hour for users
* optional syntax for multi-table deletes
* optimization for SQL_CALC_FOUND_ROWS
* a small addition for CREATE .. SELECT that will be of future use

I know that all this will require many additions to documentation, 
which I have not done, but I am at Arjen's disposal to help him document
all this.
