The 'setgroups(0, NULL);' stance works the same on all versions of
FreeBSD, getting rid of all supplementary groups.  The replaced code
would force the effective GID to also be a supplementary group.

This adds support for obtaining timestamps from IPv6 packets using the
SO_BINTIME socket option, bringing it in parity with IPv4 behavior.

Enable testing the SO_BINTIME option in the relevant (manual) regression
test.

This was prompted by noticing that '/var/db/portsnap' still exists on
newly-installed machines.

With this change, all mentions of portsnap(8) in the tree are gone,
except for the historical note in the AUTHORS section of manpage
phttpget(8).

locate(1) will thus start indexing again '/var/db/portsnap' on machines
where this directory still exists, which may be a good way to push
administrators to delete it.
