pkg:  Build with -j8 when packaging xorp.

Everyone has 8-core processors these days, right?
comm-sock:  always bind ipv6 to requested scope.

Calling code can make decision on whether to zero it out or not.

fea:  bind ipv6 udp socket with BINDTODEV and scope.

Use scope regardless of link-local addr or not, if we
can find the ifindex.

Doesn't appear to have much changes in my testing, but
looks more proper to me.

ripng:  bind to specific ipv6 addr.

This lets us run more than one ripng per OS, and should
also do a better job of restricting reception of pkts on
ports we do not care about.

rip:  comments and commented-out logging.

Should be no functional change, but will be easier to
debug in future should need arise.
