makepatch, update-patches, patchtool

[Christian Weisgerber]

We have (at least) three helpers in the ports tree for creating and
updating patch-* files:

* makepatch
  bsd.port.mk target, self-contained

* update-patches
  bsd.port.mk target, calls Tools/scripts/update-patches
  (originally taken from OpenBSD but not synced in a long time)

* patchtool
  Tools/scripts/patchtool.py

Is it time to trim some of those?  I'm under the impression that
"makepatch" is currently the favored one.  Any reason to keep the
others?
