dlenev@mysql.com da2af0bb6d Fix for bug #12423 "Deadlock when doing FLUSH PRIVILEGES and GRANT in ...

multi-threaded environment".

To avoid deadlocks between several simultaneously run account management 
commands (particularly between FLUSH PRIVILEGES/SET PASSWORD and GRANT
commands) we should always take table and internal locks during their
execution in the same order. In other words we should first open and lock
privilege tables and only then obtain acl_cache::lock/LOCK_grant locks.
