by binlogging some SET ONE_SHOT CHARACTER_SETetc,
which will be enough until we have it more compact and more complete in 5.0. With the present patch,
replication will work ok between 4.1.3 master and slaves, as long as:
- master and slave have the same GLOBAL.COLLATION_SERVER
- COLLATION_DATABASE and CHARACTER_SET_DATABASE are not used
- application does not use the fact that table is created with charset of the USEd db (BUG#2326).
all of which are not too hard to fulfill. 
ONE_SHOT is reserved for internal use of mysqlbinlog|mysql and works only for charsets,
so we give error if used for non-charset vars.
Fix for BUG#3875 "mysqlbinlog produces wrong ouput  if query uses
 variables containing quotes" and BUG#3943 "Queries with non-ASCII literals are not replicated
 properly after SET NAMES".
Detecting that master and slave have different global charsets or server ids.

will disable warnings, --log-warnings will increment warning level by one, or the
level can be given as an optional argument. Default level is 1.

Changed aborted connection warning to be logged only if the level is > 1.

--with-geometry and
--with-embedded-privilege-control
configure switches added

Added tests for archive. Cleaned up a merge mistake and added some information on how well archive compresses. 

Update of VC++ project files.

Ensured that all projects compile
Removed compiler warnings
Better setting of server_version variable.
Fix that make_win_src_distribution creates the privilege tables.

(fix by our Harrison Fisk): when one does SET GLOBAL SERVER_ID=x, we must set
server_id_supplied to 1.

work as expected": precision-losing conversion removed from 
sys_var_thd_ulonglong.

Changed 'SHOW FIELD STATUS' to use 'Engine' instead of 'Type'

fixed IN subselect with basic constant left expression
SQLCOM_CREATE_TABLE, SQLCOM_UPDATE_MULTI, SQLCOM_REPLACE_SELECT, SQLCOM_INSERT_SELECT, QLCOM_DELETE_MULTI fixed to be compatible with PS (BUG#3398, BUG#3406)
fixed multiupdate privelege check (BUG#3408)
fixed multiupdate tables check (BUG#3411)
unchecked commands now is rejected by PS protocol to avoid serever crash
fixed cleunup procedure to be compatible sith DO/SET (BUG#3393)

Fixed bugs in group_concat with ORDER BY and DISTINCT (Bugs #2695, #3381 and #3319)
Fixed crash when doing rollback in slave and the io thread catched up with the sql thread
Set locked_in_memory properly

I can't see group_concat_max_len in a list of variables

SET character_set_xxx=NULL
and
SET collation_xxx=NULL

that it tested the privilege in ::update() whereas it should be
in ::check() (see email from Serg, subject
"Re: bk commit - 4.1 tree (guilhem:1.1706)").
So I add instead a check_func function to sys_var_thd_bit.
I do the same addition to sys_var_thd_ulong, to unify handling
of PSEUDO_THREAD_ID with the one of SQL_LOG_BIN. So class
sys_var_pseudo_thread_id is not needed anymore, removing it.

user is not SUPER, instead of setting the value but ignoring it
silently internally.

client library:
- implemented 'check_license' function

re-using unused LOCK_active_mi to serialize all administrative
commands related to replication:
START SLAVE, STOP SLAVE, RESET SLAVE, CHANGE MASTER, init_slave()
(replication autostart at server startup), end_slave() (replication
autostop at server shutdown), LOAD DATA FROM MASTER.
This protects us against a handful of deadlocks (like BUG#2921
when two START SLAVE, but when two STOP SLAVE too).
Removing unused variables.

Note: the patch removes an extra declaration of
the read_only variable. It also assumes that '_'
sorts before [a-z].

Allow one to force lower_case_table_names to 0, even if the file system is case insensitive. This fixes some issues on Mac OS X (Bug #2994)
Added variables "lower_case_file_system", "version_compile_os" and "license"

Setting insert delayed threads = 0 at mysql_init_command.

fixed linking query_prealloc_size to query cache presence

- server-side variable 'license' added
