fixed memory leacks

(Note: test 'union' fails, but Sanja promised to fix this)

fixed layout

fixed bug of calling setup_fields without correct lex->current_select pointer in mysql_derived
more correct creation of reference in Item_field::fix_field

This fixed some optimization problems when using -DBIG_TABLES
Portabilty fixes for OpenUnix and HPUX
Added C and C++ version numbers to mysqlbug

Changed timestamp to return string in YYYY-MM-DD HH:MM:SS format.
DATE_ADD() and related functions now returns correct DATE/DATETIME type depending on argument types.
Now all tests passes, still some work left to remove warnings in log files from mysql-test-run

Class for sending data from server to client (Protocol)
This handles both the old ( <= 4.0 ) protocol and then new binary protocol that is used for prepared statements.

Optimized SELECT DISTINCT ... ORDER BY ... LIMIT
Fixed reference to uninitalized variable

fixed layout

Added CEIL as an alias for CEILING
Cleaned up CHECK constraint handling.
(We don't anymore require braces after CHECK)
Added casting to CHAR.

prevent using references on sum function (except HAVING clouse of current select) and forward references

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

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

as expected and returned default charset instead:
SET @x = _koi8_ru'test';
SELECT CHARSET(@x);

Make safe_mysqld a symlink to mysqld_safe in binary distribution
Fixed problem with CTRL-C when using mysqld --bootstrap

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

once for all derived functions.
I also reverted my patch for MONTH() and added a test case.
My MONTH() patch was too specific. This is a general fix.

Changed locking to external-locking
Fix client hangup for some invalid SQL queries.

fixed bug in sum function in subselect

Portability fixes for HPUX
Rename of CHECK_LOCK to IS_FREE_LOCK
Apply lower_case_table_names also to databases
Cleanup of describe code
Don't allow \ in database names

* binary XOR
* logical XOR
* CHECK_LOCK("lock_name")

Added statistics information for alarms (for bug tracking)

Enlarged STACK_BUF_ALLOC becasue of failed crash-me test
Aded new script mysql_tableinfo to make a system directory.

(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.
