SET character_set_xxx=NULL
and
SET collation_xxx=NULL

  More clear error message.

No need to check for result existence any more, store_result functions
now are shorter.
cli_read_binary_rows rewritten to handle MYSQL_DATA directly.

we should call check_user in NO_EMBEDDED_ACCESS_CHECKS case
to do necessary initializations

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.

"Running ANALYZE TABLE on bdb table inside a transaction hangs server thread"

1. added new status HA_ADMIN_REJECT and processing of it in mysql_admin_table
2. got ha_berkley::analyze to return HA_ADMIN_REJECT if there are any 
 transactions with the table..

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

init the binlog_cache (THD::transaction.trans_log).
I have checked all places where trans_log is used, because as now
it may not be inited in some cases, we have to be cautious
(will forward this commit mail to Heikki).
