Changed ACL_USER.user from char * to LEX_STRING.
Refactored every section that made use of ACL_USER.user as a char*.
This was done so as to be able to quickly check the hash_key of the acl_user.
Description: Fix for bug CVE-2012-5611 (bug 67685) is
incomplete. The ACL_KEY_LENGTH-sized buffers in acl_get() and
check_grant_db() can be overflown by up to two bytes. That's
probably not enough to do anything more serious than crashing
mysqld.
Analysis: In acl_get() when "copy_length" is calculated it
just adding the variable lengths. But when we are using them
with strmov() we are adding +1 to each. This will lead to a
three byte buffer overflow (i.e two +1's at strmov() and one
byte for the null added by strmov() function). Similarly it
happens for check_grant_db() function as well.
Fix: We need to add "+2" to "copy_length" in acl_get()
and "+1" to "copy_length" in check_grant_db().

includes:
* remove some remnants of "Bug#14521864: MYSQL 5.1 TO 5.5 BUGS PARTITIONING"
* introduce LOCK_share, now LOCK_ha_data is strictly for engines
* rea_create_table() always creates .par file (even in "frm-only" mode)
* fix a 5.6 bug, temp file leak on dummy ALTER TABLE
- temporary tables now works
- mysql-system_tables updated to not use temporary tables
- PASSWORD() function fixed
- Support for STATS_AUTO_RECALC, STATS_PERSISTENT and STATS_SAMPLE_PAGES table options
mysql-test/include/wait_show_condition.inc:
Print failing statement if timeout
mysql-test/r/myisam-metadata.result:
Updated DBUG_SYNC
mysql-test/t/myisam-metadata.test:
Updated DBUG_SYNC.
Removed wait_show_condtion, as this is not needed when we use DBUG_SYNC
This should fix timing issues with the test

Users can set different repplication filter rules for each replication connection, in my.cnf or command line.
But the rules set online will not record in master.info, it means if users restart MySQL, these rules will lose.
So if users wantn't their replication filter rules lose, they should write the rules in my.cnf.
Users can set rules by 2 ways:
1. Online SET command, "SET connection_name.replication_filter_settings = rules;".
2. In my.cnf, "connection_name.replication_filter_settings = rules".
If no connection_name in my.cnf, this rule will apply for ALL replication connection.
If no connetion_name in SET statement, this rull will apply for default_connection_name.
