Implement a new virtio_9p device to be used for sharing directories with
the VM.

BUG=chromium:703939
TEST=mount inside a VM and run `bonnie++ -r 256`
Append the shared directory to the crosvm command line:
--shared-dir /path/to/dir:test_9p
Then mount in the guest:
mkdir /tmp/9p
mount -t 9p -o trans=virtio test_9p /tmp/9p -oversion=9p2000.L
Or for a 9p root:
run --shared-dir /mnt/vm_root:/dev/root -p 'root=/dev/root ro rootflags=ro,trans=virtio,version=9p2000.L,cache=loose rootfstype=9p' vmlinux.bin
