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copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong.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

# FindHDF5
# --------
#
# Find HDF5, a library for reading and writing self describing array data.
#
#
#
# This module invokes the HDF5 wrapper compiler that should be installed
# alongside HDF5. Depending upon the HDF5 Configuration, the wrapper
# compiler is called either h5cc or h5pcc. If this succeeds, the module
# will then call the compiler with the -show argument to see what flags
# are used when compiling an HDF5 client application.
#
# The module will optionally accept the COMPONENTS argument. If no
# COMPONENTS are specified, then the find module will default to finding
# only the HDF5 C library. If one or more COMPONENTS are specified, the
# module will attempt to find the language bindings for the specified
# components. The only valid components are C, CXX, Fortran, HL, and
# Fortran_HL. If the COMPONENTS argument is not given, the module will
# attempt to find only the C bindings.
#
# On UNIX systems, this module will read the variable
# HDF5_USE_STATIC_LIBRARIES to determine whether or not to prefer a
# static link to a dynamic link for HDF5 and all of it's dependencies.
# To use this feature, make sure that the HDF5_USE_STATIC_LIBRARIES
# variable is set before the call to find_package.
#
# To provide the module with a hint about where to find your HDF5
# installation, you can set the environment variable HDF5_ROOT. The
# Find module will then look in this path when searching for HDF5
# executables, paths, and libraries.
#
# Both the serial and parallel HDF5 wrappers are considered and the first
# directory to contain either one will be used. In the event that both appear
# in the same directory the serial version is preferentially selected. This
# behavior can be reversed by setting the variable HDF5_PREFER_PARALLEL to
# true.
#
# In addition to finding the includes and libraries required to compile
# an HDF5 client application, this module also makes an effort to find
# tools that come with the HDF5 distribution that may be useful for
# regression testing.
#
# This module will define the following variables:
#
# ::
#
# HDF5_FOUND - true if HDF5 was found on the system
# HDF5_VERSION - HDF5 version in format Major.Minor.Release
# HDF5_INCLUDE_DIRS - Location of the hdf5 includes
# HDF5_INCLUDE_DIR - Location of the hdf5 includes (deprecated)
# HDF5_DEFINITIONS - Required compiler definitions for HDF5
# HDF5_LIBRARIES - Required libraries for all requested bindings
# HDF5_HL_LIBRARIES - Required libraries for the HDF5 high level API for all
# bindings, if the HL component is enabled
#
# Available components are: C CXX Fortran and HL. For each enabled language
# binding, a corresponding HDF5_${LANG}_LIBRARIES variable will be defined.
# If the HL component is enabled, then an HDF5_${LANG}_HL_LIBRARIES will
# also be defined. With all components enabled, the following variables will be defined:
#
# ::
#
# HDF5_C_LIBRARIES - Required libraries for the HDF5 C bindings
# HDF5_CXX_LIBRARIES - Required libraries for the HDF5 C++ bindings
# HDF5_Fortran_LIBRARIES - Required libraries for the HDF5 Fortran bindings
# HDF5_C_HL_LIBRARIES - Required libraries for the high level C bindings
# HDF5_CXX_HL_LIBRARIES - Required libraries for the high level C++ bindings
# HDF5_Fortran_HL_LIBRARIES - Required libraries for the high level Fortran
# bindings.
#
# HDF5_IS_PARALLEL - Whether or not HDF5 was found with parallel IO support
# HDF5_C_COMPILER_EXECUTABLE - the path to the HDF5 C wrapper compiler
# HDF5_CXX_COMPILER_EXECUTABLE - the path to the HDF5 C++ wrapper compiler
# HDF5_Fortran_COMPILER_EXECUTABLE - the path to the HDF5 Fortran wrapper compiler
# HDF5_C_COMPILER_EXECUTABLE_NO_INTERROGATE - path to the primary C compiler
# which is also the HDF5 wrapper
# HDF5_CXX_COMPILER_EXECUTABLE_NO_INTERROGATE - path to the primary C++
# compiler which is also
# the HDF5 wrapper
# HDF5_Fortran_COMPILER_EXECUTABLE_NO_INTERROGATE - path to the primary
# Fortran compiler which
# is also the HDF5 wrapper
# HDF5_DIFF_EXECUTABLE - the path to the HDF5 dataset comparison tool
#
# The following variable can be set to guide the search for HDF5 libraries and includes:
#
# HDF5_ROOT
