Drew Galbraith 9b43d615a9 [Zion] Split free physical memory into two lists. 
Allow partitioning create requests so for large continuous requests
we don't have to iterate past a bunch of single free pages.

Drew Galbraith 126482f3e8 [Yellowstone] Release init caps after loading. 
This was incredibly helpful for finding cases where we were using
uninitialized memory as it causes a lot more pages to be reused early.

Drew Galbraith 0f2d6d7cc8 [Mammoth] Load non aligned ELF program sections properly. 
Previously we would write into a memory object for an offset address but
when it would be mapped into the address space it would be page aligned.

Drew Galbraith 0ced0032ff Move qemu startup to its own script. 
This causes us to reinstall and rebuild the image each time
we run qemu. This necessary now that we are loading files
from the disk because cmake makes it tricky (impossible?) to
have a command rely on a different target being "installed".

Because of this, updates to the teton executable were not being
picked up on the image.
