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

Move kernel to higher half.
...
Return to having the bootloader re-map the kernel into the higher
half before jumping into the kernel entrypoint, so we don't have
to juggle pointers inside the kernel.

Map is still identity-mapped. I think we need to sort and/or clean up

Kernel image now has a header with version, magic number, and a
pointer to its actual entrypoint. Entry point is now _start in
boot.s, and we now generate versions.s in the build tree for the
version macros.
