Import a subset of PF distribution files

Browse Source 
We do not support any PF functionality, nor do we intend to.  However,
some NetBSD utilities rely on the presence of these files.  Not all of
the files are installed.  The NetBSD source seems rather inconsistent
in where from to include these files.  We simply follow what NetBSD
does, though.
