Other changes done to get this to work: - Added 'internal_tables' to TABLE object to list which sequence tables is needed to use the table. - Mark any expression using DEFAULT() with LEX->default_used. This is needed when deciding if we should open internal sequence tables when a table is opened (we don't need to open sequence tables if the main table is only used with SELECT). - Create_and_open_temporary_table() can now also open all internal sequence tables. - Added option MYSQL_LOCK_USE_MALLOC to mysql_lock_tables() to force memory allocation to be used with malloc instead of memroot. - Added flag to MYSQL_LOCK to remember if allocation was done with malloc or memroot (makes code simpler and safer). - init_one_table_for_prelocking() now takes argument for what lock to use instead of it's a routine or something else. - Renamed prelocking placeholders to make them more understandable as they are now used in more code. - Changed test in check_lock_and_start_stmt() if found table has correct locks. The old test didn't work for tables that has lock TL_WRITE_ALLOW_WRITE, which is what sequence tables are using. - Added VCOL_NOT_VIRTUAL option to ensure that sequence functions can't be used with virtual columns - More sequence tests
