The parser of CREATE USER accepts ACCOUNT LOCK before PASSWORD
EXPIRE but not the other way around.
This just changes the SHOW CREATE USER to output a sql syntax that
is valid.
Thanks to Robert Bindar for analysis.
Add server support for user account locking.
This patch extends the ALTER/CREATE USER statements for
denying a user's subsequent login attempts:
ALTER USER
user [, user2] ACCOUNT [LOCK | UNLOCK]
CREATE USER
user [, user2] ACCOUNT [LOCK | UNLOCK]
The SHOW CREATE USER statement was updated to display the
locking state of an user.
