[PATCH] Merge to current SVN repo (r915)

Changes:

  - Convert to a static highlevel handle for all drivers. Gets rid of
    a kmalloc for each driver and consolidates the highlevel handle and
    highlevel ops. Reduces points of failure as well.
  - Move host number allocation to hosts.c, giving all drivers access to
    it.
  - Implemented S800 changes for core and sbp2. Thanks to TI and LaCie
    for hardware to test this. 1394b support coming soon.
  - Convert nodemgr to using a similar device classification hack as
    usb. The old class_num hack I had in place was broken do to its
    removal. This is a much cleaner solution.
