Two bugs fixed wrt vm restartability.
. make sure pagetable data is only allocated
using dynamic data instead of static spare pages
(bootstrap pages). They are needed for bootstrap
but now repeat some of the initialization so only
dynamic data remains. This solves the problem of
physical addresses changing (as static pages are
re-allocated for the new instance) after update.
. pt_ptalloc has to be specified in bytes instead of
pde slot numbers. leaving pt_pt NULL causes mapping
transfers to fail because NULL happens to be mapped in
then and updates then happen there.
. added some sanity checks against the above happening.
The new state is that VM can update many times, but the system
isn't fully reliable afterwards yet.
