7dfe24ee2c Rework kboot/chainload flow to shut down before calling the next stage 
Next stage boots now exit back to main() after replying to the proxy
command, allowing shutdown functions to be called. Introduces a new
P_VECTOR proxy op, distinct from P_CALL. The Python side is reworked
to remain compatible with older versions that do not support this.

b8349819fe Implement calling code as EL1 
This works by clearing HCR_EL2.TGE, and then doing essentially the same
thunk/return dance as for EL0 calls. However, since most EL1 exceptions
are not routed to EL2, we install hypercall vectors in EL1 to forward
them to EL2, and then short circuit the exception return to whatever
triggered the original exception.

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.

which might have side effects on RAM, so just make everything a memory
