Paul Durrant 3284fad728 xen-disk: add support for multi-page shared rings 
The blkif protocol has had provision for negotiation of multi-page shared
rings for some time now and many guest OS have support in their frontend
drivers.

This patch makes the necessary modifications to xen-disk support a shared
ring up to order 4 (i.e. 16 pages).
