Boilerplate copyright/license adjustment preparation

Squid-3 is now being administered by the Squid Software Foundation,
a non-profit organisation created for the purpose of providing
governance and representation for the Squid Project and community
of contributors.
  http://www.squid-cache.org/Foundation/

As such the Squid source code collection is being prefixed with a
new copyright blurb:

 * Copyright (C) 1996-2014 The Squid Software Foundation and contributors
 *
 * Squid software is distributed under GPLv2+ license and includes
 * contributions from numerous individuals and organizations.
 * Please see the COPYING and CONTRIBUTORS files for details.

Existing copyright claims on specific source code files are being
preserved in-situ following this collection blurb.

With some exceptions where existing copyright owners have explicitly
given permission for their specific claim statements to be moved to
the CONTRIBUTORS file and assist removal of the inconsistent and
now often incorrect Harvest and Squid Project blurb(s).

This patch publishes the script and boilerplate text used to perform
this change of copyright marking for public review.

Also, adds some administrative polishing in preparation for the
blurb adjustments.

  This is a Squid Software Foundation project.
