Introduces the Xen pvUSB frontend. With pvUSB it is possible for a Xen
domU to communicate with a USB device assigned to that domU. The
communication is all done via the pvUSB backend in a driver domain
(usually Dom0) which is owner of the physical device.
The pvUSB frontend is a USB hcd for a virtual USB host connector.
The code is taken from the pvUSB implementation in Xen done by Fujitsu
based on Linux kernel 2.6.18.
Changes from the original version are:
- port to upstream kernel
- put all code in just one source file
- move module to appropriate location in kernel tree
- adapt to Linux style guide
- minor code modifications to increase readability

This looks sane to me, but I don't know the HCD interface as well as
others on linux-usb do, like Alan Stern.
What tree do you want this to be merged through, my USB one?
