Log message:
Initial import of Leafnode 1.9.22 into the NetBSD packages collection
as news/leafnode.

Leafnode is a USENET software package designed for small sites, with a
few tens of readers and only a slow link to the net.

The work in this package is based on that of Ingolf Steinbach 
in PR#13830. wiz@ made some suggestions as well. Thanks to both of them.
