Copy the value to our `ConfigName` member on construction to ensure it
is available even to code paths that run before `Generate`. We once
needed to delay this lookup until `Generate` because the local
generators were at one time created before `Configure`. Now they are
created at generate time which is late enough to expect
`CMAKE_BUILD_TYPE` to be available.
Without this, `cmGlobalUnixMakefileGenerator3::WriteConvenienceRules`
causes use of `ConfigName` before it is populated which breaks use of
source files that depend on the `$<CONFIG>` generator expression.
Fixes: #16889
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names and years are hard to maintain and often out-of-date or plain wrong.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.
Add a cmLocalGenerator::GetTargetFortranFlags virtual method to get
generator-specific generation of Fortran-specific flags. Implement it
in cmLocalCommonGenerator by moving the implementation from
cmCommonTargetGenerator::AddFortranFlags. This will allow it to be used
without having a target generator available.

Run the `Utilities/Scripts/clang-format.bash` script to update
all our C++ code to a new style defined by `.clang-format`.
Use `clang-format` version 3.8.
