  Log:
  Implement (non-bootable) GPT support.  If a PMBR partition type is detected
  the rest of the MBR is ignored and the GPT partition table will be parsed
  into slices.  GPT partition 0 will be s0, GPT partition 1 will be s1, etc.
  Bootable support is forthcoming.
  
  Remove support for COMPATIBILITY_SLICE when a MBR/GPT table is present.  That
  is, the COMPATIBILITY_SLICE (s0) will still point to the dangerously
  dedicated disklabel or be synthesized for a CD, but it will no longer point
  to the 'first BSD slice' in a real MBR or GPT table.  For GPT tables
  slice 0 (s0) will point at GPT partition #0, slice 1 (s1) at
  GPT partition #1, etc.
  
  Redo the reserved sector handling code.  There is now a single reserved
  sector count instead of separate fields for the slice layer and disklabel
  layer.
  
  Redo the disklabel snooping code.  Note that you cannot run an old
  /sbin/disklabel in raw (-r) mode with a new OS because the old disklabel
  will not turn on snooping.  For now the on-disk format remains the same,
  but more changes may be forthcoming (after discussion).  I would like to
  get rid of the snooping entirely.
  
  Add kuuid_is_nil() and use it to ignore unset GPT paritions.
