James Harvey points out that entering an invalid game ID can affect
the current midend state even if you don't subsequently enter a valid one. Reorganise midend_game_id_int() so that (just like midend_deserialise()) it does all its error checking before altering anything in the midend's persistent data, so that it either succeeds completely or fails before doing anything at all. [originally from svn r6045]
