Bootstrapping SEPOS requires to setup a scratch buffer and
will have to be handled by the final OS. We pass along
the firmware image by appending it to the initramfs.

Read the MAC addresses from the ADT and store them in
"local-mac-address" properties on the relevant nodes in the FDT.
This relies on appropriate aliases in the provided FDT, which
matches how U-Boot provides MAC addresses on embedded targets.

at the same time.

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.

Turns out we had a bunch of silly dependencies on libc headers that are
not included with freestanding compilers. Fix all this and change the
CFLAGS to exclude libc headers and only include the built-in compiler
path.
Add our own versions of assert.h, errno.h, limits.h, and move malloc.h
and string.h together into a new path used as -isystem, so these headers
can be included using #include <>.
Remove a bunch of other dependencies in third-party code.
Add a strnlen function.
Disable building the libfdt overlay code for now, as it needs a strtoul
implementation. We can throw that in if/when we decide to use overlays.
