Adding support for HP Service Partition GUID for GPT

[Richard Hirst]

Hi,
  HP have defined a Service Partition GUID for their ia64 systems.  It
is a partition with FAT filesystem, holding various diagnostic and
configuration tools (like compaq-diag, dell-diag, etc).  We need to be
able to create partitions with this GUID, and recognise from parted
print output when such a partition exists.  At the moment I'm concerned
with getting support for this in to parted 1.4, but will do what is
necessary for 1.6 if this is accepted.  I've included a patch below for
comment.

Thanks,
  Richard
