Move to static trampolines and type-safe hooks
For some reason the DLL got a tiny little bit bigger again but that's
fine. This will make orig_ calls more efficient in the inline case, and
also make it harder to screw up and hook the wrong thing by mistake.
Self-explanatory-ish, apart from the fact it's a fairly large API change
of course. And it relies on some more bonkers assembler directive
hackery.
But it works!
The only complaint one might have is that the featsetup functions no
longer take an explicit string which occasionally yields slightly less
perfect error messages, but I've decided this isn't really a problem and
makes the API nicer to use. It's a tradeoff, innit.
