Speed up DeviceKit device probing on really slow devices

Hey,

Thanks for the patch - I just applied it:

http://cgit.freedesktop.org/DeviceKit/DeviceKit-disks/commit/?id=c8076f0095ce85b10b287e6c5d92f8b5520018f2

As Kay said on the util-linux-ng list, the plan is to use blkid for this
in the future - so at some point udisks-part-id will go away.

Actually, I *think* the code is already in blkid for this - but IIRC a
few details such as partition flags are still missing (see e.g.
http://people.freedesktop.org/~david/gdu-edit-partition.png for how this
information is used)

Thanks,
David
