7a84b2bbf9 tools/run_guest_kernel.sh: Support concatenated initramfs images
This allows booting a kernel with the firmware cpio and a cpio
containing matching modules. The modules initramfs can be prepared from
the kernel source directory with:

`make dir-pkg && usr/gen_initramfs.sh -o initramfs_mod.cpio -u squash -g squash ./tar-install/lib/`

The modules are available in /modules/$(uname -r) and the initramfs can
handle modules in the same way as the vendor firmware to make them
available for itself and the main OS.

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.
