Changes

If a bug has one or more security groups applied to it, that is, it has restricted visibility, any Differential revisions associated with it will similarly be restricted in visibility. This will initially only apply to Firefox security groups, that is, groups with names matching ''*core-security*''. Any revision associated with a bug restricted via other groups, e.g. infra, will be visible only to the author and admins. We can add proper support for such groups on request.

For simplicity, and since Differential's review system does not map cleanly to BMO's review flags, r+ flags, and only r+ flags, will be set on the stub attachment associated with a Differential revision when a Phabricator user performs an "Accept Revision" action. The flag will be removed if the user later issues a "Request Changes" or a "Resign as Reviewer" action. Similarly, all r+ flags will be removed if the author selects any of the "Plan Changes", "Request Review", or "Abandon Revision" actions.
