Brad King 86578eccf2 Simplify CMake per-source license notices
Per-source copyright/license notice headers that spell out copyright holder
names and years are hard to maintain and often out-of-date or plain wrong.
Precise contributor information is already maintained automatically by the
version control tool.  Ultimately it is the receiver of a file who is
responsible for determining its licensing status, and per-source notices are
merely a convenience.  Therefore it is simpler and more accurate for
each source to have a generic notice of the license name and references to
more detailed information on copyright holders and full license terms.

Our `Copyright.txt` file now contains a list of Contributors whose names
appeared source-level copyright notices.  It also references version control
history for more precise information.  Therefore we no longer need to spell
out the list of Contributors in each source file notice.

Replace CMake per-source copyright/license notice headers with a short
description of the license and links to `Copyright.txt` and online information
available from "https://cmake.org/licensing".  The online URL also handles
cases of modules being copied out of our source into other projects, so we
can drop our notices about replacing links with full license text.

Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority
of the replacements mechanically.  Manually fix up shebang lines and trailing
newlines in a few files.  Manually update the notices in a few files that the
script does not handle.

# NOTE: It is highly recommended that you use the new
# FindOpenSceneGraph.cmake introduced in CMake 2.6.3 and not use this
# Find module directly.
#
# This is part of the Findosg* suite used to find OpenSceneGraph
# components. Each component is separate and you must opt in to each
# module. You must also opt into OpenGL and OpenThreads (and Producer
# if needed) as these modules won't do it for you. This is to allow you
# control over your own system piece by piece in case you need to opt
# out of certain components or change the Find behavior for a particular
# module (perhaps because the default FindOpenGL.cmake module doesn't
# work with your system as an example). If you want to use a more
# convenient module that includes everything, use the
# FindOpenSceneGraph.cmake instead of the Findosg*.cmake modules.
#
# Locate osg This module defines
#
# OSG_FOUND - Was the Osg found? OSG_INCLUDE_DIR - Where to find the
# headers OSG_LIBRARIES - The libraries to link against for the OSG (use
# this)
#
# OSG_LIBRARY - The OSG library OSG_LIBRARY_DEBUG - The OSG debug
# library
#
# $OSGDIR is an environment variable that would correspond to the
# ./configure --prefix=$OSGDIR used in building osg.
