Andrew Boie 8014e075f4 x86: use per-thread page tables 
Previously, context switching on x86 with memory protection
enabled involved walking the page tables, de-configuring all
the partitions in the outgoing thread's memory domain, and
then configuring all the partitions in the incoming thread's
domain, on a global set of page tables.

We now have a much faster design. Each thread has reserved in
its stack object a number of pages to store page directories
and page tables pertaining to the system RAM area. Each
thread also has a toplevel PDPT which is configured to use
the per-thread tables for system RAM, and the global tables
for the rest of the address space.

The result of this is on context switch, at most we just have
to update the CR3 register to the incoming thread's PDPT.

The x86_mmu_api test was making too many assumptions and has
been adjusted to work with the new design.
