9e9693eb6c rust: Switch to RUSTC_BOOTSTRAP=1 backdoor instead of nightly 
Nightly is messing around with alloc_error_handler and they can't seem
to make up their mind about it, breaking our CI. Just switch to stable
rust with the usual backdoor to enable unstable features (same as the
kernel does).

6661ab14d0 hv: Add 9P virtio peripheral 
Add some minimal implementation of virtio peripherals. At the level
of on-target hypervisor code we implement the MMIO layout and
maintain virtqueues. Once a buffer is available, we break into the
host proxyclient to deal with it.

Specific device-classes of the virtio spec ought to be implemented in
the proxyclient. Here the one device implemented is 9P transport,
exporting the m1n1 source directory.

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
