. VM needs a higher priority than VFS, PM etc

. introduce FULLVM flag: MEMORY and the initial MFS
get their own full address spaces, making their stacks
and heaps not preallocated (well, freed after VM has
initialized it) and letting them allocate more dynamically.
MEMORY in particular needs this to map in physical memory
using its own page table, without having to allocate.
