4575b35479 rust: Initial Rust-based EFI FAT32 chainloader
This code is gated behind the CHAINLOADING define. To build a
release-style m1n1 with chainloading for use with the installer
or kmutil, use:

make CHAINLOADING=1 RELEASE=1

To tell m1n1 to chainload another binary, use this var payload:

chainload=<ESP partition UUID>;<file path>

e.g.

chainload=a17b7e46-e950-bb4f-bc82-8ab1047a058e;m1n1/m1n1.bin

Closes: #154

e386e17550 chainload: Add new m1n1-side chainloader (raw images only)
This basically duplicates the chainload.py logic, minus the mach-o
handling.

d73276b0bc tunables: add initial version.
There are at least two types in the ADT related to USB,
but there's a decent chance that there are even more
required for other devices:

 * A simple tunable that applies to a whole device node
   and all its MMIO ranges specified in the "reg" property.
   This one seems to just be mask32.

 * A slightly more complex tunable that applies to a single
   MMIO range specified in the "reg" property. So far I've
   only seen 32 bit masks but the format looks like it should
   also support 8,16 and 64 bit masks.

efa4452a47 Fix libc header dependencies
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.
