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names and years are hard to maintain and often out-of-date or plain wrong.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.

# CMakeGraphVizOptions
# --------------------
#
# The builtin graphviz support of CMake.
#
# Variables specific to the graphviz support
# ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
#
# CMake
# can generate graphviz files, showing the dependencies between the
# targets in a project and also external libraries which are linked
# against. When CMake is run with the --graphviz=foo option, it will
# produce
#
# * a foo.dot file showing all dependencies in the project
# * a foo.dot.<target> file for each target, file showing on which other targets the respective target depends
# * a foo.dot.<target>.dependers file, showing which other targets depend on the respective target
#
# This can result in huge graphs. Using the file
# CMakeGraphVizOptions.cmake the look and content of the generated
# graphs can be influenced. This file is searched first in
# ${CMAKE_BINARY_DIR} and then in ${CMAKE_SOURCE_DIR}. If found, it is
# read and the variables set in it are used to adjust options for the
# generated graphviz files.
#
# .. variable:: GRAPHVIZ_GRAPH_TYPE
#
# The graph type
#
# * Mandatory : NO
# * Default : "digraph"
#
# .. variable:: GRAPHVIZ_GRAPH_NAME
#
# The graph name.
#
# * Mandatory : NO
# * Default : "GG"
#
# .. variable:: GRAPHVIZ_GRAPH_HEADER
#
# The header written at the top of the graphviz file.
#
# * Mandatory : NO
# * Default : "node [n fontsize = "12"];"
#
# .. variable:: GRAPHVIZ_NODE_PREFIX
#
# The prefix for each node in the graphviz file.
#
# * Mandatory : NO
# * Default : "node"
#
# .. variable:: GRAPHVIZ_EXECUTABLES
#
# Set this to FALSE to exclude executables from the generated graphs.
#
# * Mandatory : NO
# * Default : TRUE
#
# .. variable:: GRAPHVIZ_STATIC_LIBS
#
# Set this to FALSE to exclude static libraries from the generated graphs.
#
# * Mandatory : NO

#
# Set this to FALSE to exclude external libraries from the generated graphs.
#
# * Mandatory : NO
# * Default : TRUE
#
# .. variable:: GRAPHVIZ_IGNORE_TARGETS
#
# A list of regular expressions for ignoring targets.
#
# * Mandatory : NO
# * Default : empty
#
# .. variable:: GRAPHVIZ_GENERATE_PER_TARGET
#
# Set this to FALSE to exclude per target graphs ``foo.dot.<target>``.
#
# * Mandatory : NO
# * Default : TRUE
#
# .. variable:: GRAPHVIZ_GENERATE_DEPENDERS
#
# Set this to FALSE to exclude depender graphs ``foo.dot.<target>.dependers``.
#
# * Mandatory : NO
# * Default : TRUE
