[COMMIT] Stack rework

Heads up for internal hackers, General stacks and control stacks are no longer circular. They are now terminated at both ends with NULL pointers. A "stack" now points to the top of the stack, not the base. This simplified stack handling as well as the GC tracing, but in one case, stack_entry()

init_method_t for coroutines and subs?

I know there was some talk about this extra "address" parameter recently, but i'm not sure what the upshot of it is. Right now, tcc is complaining loudly because the init functions for parrotsub and parrotcoroutine don't match the init_method_t type in the _vtable structure. What's the deal

XML escaping, etc..

I've been meaning to ask- is there any plan to add special support for XML features such as string escaping? It would be very useful, IMHO, to have something analogous to the "\Q" feature in perl5 for escaping regexps, but which would do XML-style "<" and ">" escaping. I'm specifically inter
