passed by value (trap frames) as if they were in fact being passed by reference. For better or worse, this incorrect behaviour is no longer present in gcc 4.1. In this patch I convert all trapframe arguments to be explicitly pass by reference. I also remove vm86_initflags, pushing the very little work that it actually does up into vm86_prepcall.
