Add git-arc

[markj]

Summary

This is a script to make it easier to manage phabricator reviews for src
commits. It tries to avoid forcing any particular workflow.

I might also be convinced to write a git-arc(8) man-page. ;)

I would recommend s/verb/command/, as that's the syntax used in other places, for example camcontrol(8), which uses (sub)commands too.

That would be useful. Let's perhaps first wait and see if the interface changes much before I commit.

• Address feedback, verb -> command in the usage message.

Probably s/upstream/freebsd/ here to match our other git docs.

Agreed.

Use the canonical name for an upstream FreeBSD remote.

Is it a show-stopper that this script relies on the textproc/jq port?

I don't really expect so since it already relies on the arcanist port. But we should verify that both packages are installed before trying to do anything...

Check for jq and arc before trying to do anything.
