    Added missing sync_slave_with_master; Fixes random failures
    Had to explictely do stop slave before DROP USER to avoid failure on slave as the user is already dropped on slave.

    Don't use bit_do_set() / bot_is_set() / bit_do_clear() as this generates compiler warnings
    (They are also of no use as we know the value can hold the bits)
