delete (drop) tables.
SYNOPSIS
mysql_rm_table_part2_with_lock()
thd Thread handle
tables List of tables to delete
if_exists If 1, don't give error if one table doesn't exists
dont_log_query Don't write query to log files. This will also not
generate warnings if the handler files doesn't exists
NOTES
Works like documented in mysql_rm_table(), but don't check
global_read_lock and don't send_ok packet to server.
RETURN
0 ok
1 error
