Switch to 3.0 (quilt) source format with custom patch header

* Switch to 3.0 (quilt) source format.  Force a single Debian patch and
  include a custom patch header explaining that it is a rollup of any
  fixes cherry-picked from upstream and breaking those patches out
  separately would be work for no gain.

+Subject: Collected Debian patches for remctl
+Author: Russ Allbery <rra@debian.org>
+
+Since I am also upstream for this package, there will normally not be any
+patches to apply to the upstream source.  However, occasionally I'll pull
+up specific upstream commits prior to making an upstream release.  When
+this happens, this patch will collect all of those modifications.
+
+I use Git to maintain both the upstream source and the Debian packages,
+and generating individual patches rather than using git cherry-pick takes
+extra work for no gain.  Since I'm also upstream, there's no need to
+separate the patches for later upstream submission.  Hence, I take this
+approach with a unified patch when it's necessary.
+
+For full commit history and separated commits, see the upstream Git
+repsitory.
