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.

3872b1a7da exception: implement el0_call to run code as EL0 
This lets us test register access and other features from EL0.

No serious attempt at security is made, but at least EL0 runs off of a
separate stack and can return to EL2 at any time with `brk`; we can
easily implement a guard mode to break straight to EL2 on exception
later if needed.

73a85be2b8 memory: prepare for EL0 support 
Enable EL0 access to MMIO/etc, but not main RAM, because AArch64
architecturally enforces EL0w ^ EL2x.

Instead, create an alias of main RAM to grant EL0 full permissions,
at 0x80_0000_0000.

Grant EL0 full access to MMIO stuff, since EL2 will never execute
from there.

(5.6M uncompressed, 2.1M gz and 1.6M xz). Compression method is
autodetect by the filename suffix or can be set by the '--compression'
command line option.
Also supports uncompressed payloads (no auto detection).

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.
