Update cdbs snippets, copyright-hints and dependencies.

* Update cdbs snippets:
  + Move dependency cleanup to new local snippet package-relations.mk.
  + Update copyright-check output to more closely match proposed new
    copyright file format.  Update copyright-hints.
  + Minor improvements to flavor-enhanced autotools- and makefile-
    snippets.
  + Update README.cdbs-tweaks.
* Add DEB_MAINTAINER_MODE in debian/rules (thanks to Romain Beauxis).
* Semi-auto-update debian/control to update dependencies:
  DEB_MAINTAINER_MODE=1 fakeroot debian/rules clean
