Hi all,

        A few more cleanups for our simplified I/O prototype.  This code adds a
"vdevice" bus for share-I/O devices: with simpler I/O comes simpler
setup and teardown, so xenbus is overkill.  This "bus" is initialized
correctly by the xm tools now, but for the moment a simple standalone
"vdevice" tool is used to add/remove devices.

        Various other archs (PPC, ia64) indicated that they needed some API
abstraction for my simple share I/O interface: I've finally supplied it.
This should allow porting for those archs fairly trivially.

        We are planning a slight modification to the share API to support Van
Jacobson netchannels, but don't foresee fundamental changes.  We'll also
update to the latest Xen tree, and start proper Xen tool integration.
