1de73de2e3 Move page table allocation to top 256GiB. 
I forgot to account for tracking page table physical addresses, so
this is a bit of an overhaul. Major changes:
- Refactor bootstrap code into more functions and:
  - Only allocate 32 pages of scratch space
  - Remap remaining space into top 256GiB, the "page table space"
- Use the page table space to directly offset-map page table pages
  from their physical addresses, to avoid tracking overhead.
- Refactor page_block list functions into static functions to better
  handle null/empty lists

95d52b87f4 Initialize page_manager. 
Page manager now:
- Caches mapped pages and page_block structs
- Can unmap memory ranges
- Unmaps extra kernel memory during it's init

5dedd2e0e0 Finish memory bootstrap sequence. 
Now we're setting up all our own page tables, and handing off to
page_manager's init function. (Which is still NYI.)

57abb03deb Rearrange memory manager into two classes. 
page_manager and memory_manager are now separate, and are also pre
allocated in the kernel so they don't have to allocate themselves.
