Add a `cmGeneratorTarget::GetEffectiveFolderName` helper to abstract
lookup of the `FOLDER` property in combination with checking for
generator support of folders.
Populate a local member for the sources property when the instance is
created. Pass the parameter to avoid the policy check when doing so.
Ordinarily, the GetSources function should not be called unconditionally
(at generate time), but we need to do so here in case the property is
read in a generator expression. The intent is to be able to implement
cmGeneratorTarget without requiring cmTarget.
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names and years are hard to maintain and often out-of-date or plain wrong.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.
Our buildsystem model says that the default Fortran module output
directory is the build tree directory corresponding to the source tree
`CMakeLists.txt` file adding the current target. Extend
`cmGeneratorTarget::GetFortranModuleDirectory` to allow generators to
pass in the compiler working directory. If the working directory does
not match the default Fortran module output directory then we need an
explicit module directory flag (e.g. `-J`) to tell the compiler to
put/use modules in the latter.
This does not affect the Makefile generator but will be useful for
future introduction of Fortran support to the Ninja generator.
Move code to create/get the fortran module directory from the
cmCommonTargetGenerator to cmGeneratorTarget.
Rename the ComputeFortranModuleDirectory method to
CreateFortranModuleDirectory as this method *creates* the directory if
it is missing.
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.

This happens quite often from within comparisons such as in
NamedGeneratorTargetFinder or FindGeneratorTargetImpl. It is the
top hotspot of both, number of allocations as well as number of
temporary allocations - the majority of calls lead to temporary
allocations.
In raw numbers, this patch removes ~1E6 temporary allocations of
1.5E6 temporary allocations in total when running the cmake daemon
on the KDevelop build dir. That is 2/3 of the total.
This hotspot was found with heaptrack.
