rumpusbdisk: Add USB mass storage translatorrumpusbdisk
This adds a second binary target to compile in
the rump USB stack instead of SATA/IDE using conditional
ifdefs to mostly share the code between the two translators.
This can be tested by running qemu with a USB3 controller as follows:
-drive if=none,id=usbstick,format=raw,file=/path/to/disk.img \
-device qemu-xhci \
-device usb-storage,drive=usbstick \
NB: /path/to/disk.img can be a block device on the host.
Then call grub module rumpusbdisk.static instead of rumpdisk.static
and pass ' root=part:X:device:sd0 noide' as gnumach parameters,
where X is the partition number of / within the disk/image.
(IRQ sharing still seems broken).
