Summary	0000872: note: some lua operations set errno
Description	some calls in lua set errno which can then bleed into other functionality that checks on errno assuming that it starts out as zero there are several solutions: - each call to a helper that can set errno, first resets it - we reset errno after each directlua (in fact after each lua call) - we avoid checking for errno (happens inff lib, mplib, backend writecff)
