Clean up ctrl msg handling in Linux. Remove VBD_GROW/SHRINK -- a VBD
now maps onto a single complete major/minor that is specified at
VBD_CREATE time. Also improve blkdev request_queue unplugging in the
2.6 backend driver to promote better batching.

This patch will cause xcsdump to display more verbose information about the
xcs traffic.
This includes human-readable names of the message type and subtype and
all of the parameters and their values. It's against today's
xen-unstable and has been tested against a number of xen-unstable
snapshots going back a few weeks (one line has to be removed to support
older versions of xen-unstable).
The message types displayed are configurable via a bitmask passed as a
'-v' option in xcsdump.
The code is very useful for figuring out what management tools (Xend,
VM-Tools) are actually doing. I would not have been able to write
vm-tools without it.
