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names and years are hard to maintain and often out-of-date or plain wrong.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

# FindBLAS
# --------
#
# Find BLAS library
#
# This module finds an installed fortran library that implements the
# BLAS linear-algebra interface (see http://www.netlib.org/blas/). The
# list of libraries searched for is taken from the autoconf macro file,
# acx_blas.m4 (distributed at
# http://ac-archive.sourceforge.net/ac-archive/acx_blas.html).
#
# This module sets the following variables:
#
# ::
#
# BLAS_FOUND - set to true if a library implementing the BLAS interface
# is found
# BLAS_LINKER_FLAGS - uncached list of required linker flags (excluding -l
# and -L).
# BLAS_LIBRARIES - uncached list of libraries (using full path name) to
# link against to use BLAS
# BLAS95_LIBRARIES - uncached list of libraries (using full path name)
# to link against to use BLAS95 interface
# BLAS95_FOUND - set to true if a library implementing the BLAS f95 interface
# is found
# BLA_STATIC if set on this determines what kind of linkage we do (static)
# BLA_VENDOR if set checks only the specified vendor, if not set checks
# all the possibilities
# BLA_F95 if set on tries to find the f95 interfaces for BLAS/LAPACK
#
# ######### ## List of vendors (BLA_VENDOR) valid in this module #
# Goto,OpenBLAS,ATLAS PhiPACK,CXML,DXML,SunPerf,SCSL,SGIMATH,IBMESSL,
# Intel10_32 (intel mkl v10 32 bit),Intel10_64lp (intel mkl v10 64 bit,
