Made a some new buffers thread specific and changeable.
Resize of key_buffer.
AUTO_COMMIT -> AUTOCOMMIT

Fixed bug when using auto_increment as second part of a key where first part could include NULL.

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)

Big code cleanup/review before 4.0.2 release.
...
(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.

Surgical changes in sql_select and sql_union code in order to
...
accomodate EXPLAIN properly for all possible variant of UNION's
derived tables etc ...
This also fixes all reported (and unreported) bugs when EXPLAIN is
run on UNION's.
select_describe() now has a very dirty hack to avoid some problems
with transactional tables on table unlocking.
Code speedup is possible. For the moment all that was important was
that all tests are passed.
