- move VADDR_TO_* to headers

Browse Source 
- move part of mmu handling to mmu-dependant files and extend ops
- implemented 040 mmu init. doing so I spotted a bug in ARAnyM which ignored [ID]TT0. Linux likely doesn't use them but I was too lazy touse temporary page tables. I also noticed bitfields were in wrong order, to be fixed.
