syslogd(8) already supports *sending* log messages to non-

standard ports, but it can't *receive* them (port 514 is
hardcoded).  This commit adds that missing feature.

(NB:  I actually needed this feature for a server farm where
multiple jails run with shared IP addresses, and every jail
should have its own syslogd process.)

As a side effect, syslogd now compiles with WARNS=6.
