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copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong.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.

FindIntl: New module to find Gettext libintl Add support for Sun/Uniforum/GNU gettext libintl. This belongs in CMake rather than upstream because: * There are multiple upstreams (Sun, GNU). * It may or may not be in the glibc C library depending upon the platform and build options used. Although we already have a FindGettext module, that is for the tools. This module is for the library, and is independent because it's perfectly OK to use libintl without the gettext tools (and vice versa), and they might not all be found. Add cross references between the two modules in notes to make the relationship clearer.

#.rst:
# FindIntl
# --------
#
# Find the Gettext libintl headers and libraries.
#
# This module reports information about the Gettext libintl
# installation in several variables. General variables::
#
# Intl_FOUND - true if the libintl headers and libraries were found
# Intl_INCLUDE_DIRS - the directory containing the libintl headers
# Intl_LIBRARIES - libintl libraries to be linked
#
# The following cache variables may also be set::
#
# Intl_INCLUDE_DIR - the directory containing the libintl headers
# Intl_LIBRARY - the libintl library (if any)
#
# .. note::
# On some platforms, such as Linux with GNU libc, the gettext
# functions are present in the C standard library and libintl
# is not required. ``Intl_LIBRARIES`` will be empty in this
# case.
#
# .. note::
# If you wish to use the Gettext tools (``msgmerge``,
# ``msgfmt``, etc.), use :module:`FindGettext`.
