We check the system's primary IP, to see if it's in one of the large Livermore
network blocks.

We also include fact::common in the fact type, to make sure it's loaded.

Create the /var/lib/puppet/sufact directory whenever the fact define
is used.  This means any code elsewhere to create that directory
should be removed.  (It was usually found in defaults.)

Rewrite the fact define to use current coding style.
