Merge in the newer Xenbus implementation from Linux to the Mini-OS. The new
version compiles and starts up, but I'm not really sure how to test the new
xenbus implementation.
* Added unbind_evtchn
* Copied parts of the Linux spinlock implementation to make the changes to
xenbus compared to Linux smaller. Also added a dummy rwsem implementation.
* Updated the xenbus-files
