Nothing but vnet uses libxutil -- move it there.
Makefile, xc.c, setup.py, configure, configure.in, Makefile.in:
  This doesn't use libxutil.
Makefile, Makefile.vnet, Rules.mk:
  Move libxutil into vnet since it's only used there.

Clean up vbd probing, and include hardware sector size in the probe
information. blkback ensures that all requests are aligned to
hardware sector size and returns error if this is not so.
In blkfront we now have a request_queue per vbd, with hardsect_size
set appropriately.
It is now once again possible to mount a CDROM in a domU.

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.
