A change for committers, a change for pkgsrc

Two completely separate and unrelated changes:

First, Alex Hornung has added a check to look for certain lines in a commit message, and add a MFC reminder note to the commit message if they are found.  MFC, if you haven’t heard it, means ‘merge from current’, or moving a change from dragonfly-current to the last release version.

Second, with the next quarterly release of pkgsrc coming up, there’s some old packages that will get dropped.  Speak up if you need them to stick around.
