This adds the former ports registered groups: proxy and authpf as well as the proxy user. Make sure to run mergemaster -p in oder to complete make installworld without errors. This also provides the passive OS fingerprints from OpenBSD (pf.os) and an example pf.conf. For those who want to go without pf; it provides a NO_PF knob to make.conf. __FreeBSD_version will be bumped soon to reflect this and to be able to change ports accordingly. Approved by: bms(mentor)
