7fc52bc799 Fix broken hexdumps in proxy.py 
Proxy.py has a few typos that appear if you try to use debug mode and dump a region of memory. This should fix those.

986c6730e9 Add heapblock and dlmalloc for managing memory 
heapblock is a simple `sbrk` style implementation, also useful as an
"endless" decompression buffer. dlmalloc is used on top as a malloc
implementation.

This also changes how the Python side manages its heap. We still use a
python-side malloc implementation (since this is faster), and we put the
Python heap at the m1n1 heap + 128MB, without allocating it.
Hopefully this should never step on anything m1n1 neads, and avoids
having to manage freeing across Python script calls.

f3d0a58f42 proxy: add mmu_shutdown call, use it for linux.py 
I saw at least one SError crash on Linux after doing this, but can't
repro; unclear if related to the MMU changes or not...
