Add uuidd daemon to prevent duplicate time-based UUID's

Also store the clock sequence information in a state file in
/var/lib/misc/uuid-clock so that if the time goes backwards the clock
sequence counter can get bumped.  This allows us to completely
correctly generate time-based (version 1) UUID's according to the
algorithm specified RFC 4122.
