Run the `clang-format.bash` script to update all our C and C++ code to a
new style defined by `.clang-format`, now with "east const" enforcement.
Use `clang-format` version 18.

Issue: #26123
In commit fe3f846e1b (Makefiles: Add support for building Fortran
intrinsics, 2020-11-19, v3.22.0-rc1~565^2) the property was added with
incorrect spelling `Fortran_BUILDING_INSTRINSIC_MODULES`. Add a new
property with the correct spelling. Keep the old one for compatibility.
Issue: #21463
Add a way to specify, in a portable way, to raise an error for any
warning during the link step. For that purpose, define:
* CMAKE_LINK_WARNING_AS_ERROR variable
* LINK_WARNING_AS_ERROR target property
Fixes: #25343
The following variables now support the LINKER: prefix:
* CMAKE_SHARED_LIBRARY_CREATE_<LANG>_FLAGS
* CMAKE_SHARED_MODULE_CREATE_<LANG>_FLAGS
* CMAKE_<LANG>_LINK_FLAGS
By specifying CODEGEN as an argument to add_custom_command the
custom command will be added to a codegen build target.
The intent is to provide a convenient way for users to get
their generated files without having to build the whole project.
This can be helpful for code analysis tools which can be useful
for IDEs and CI.
Since commit f593b354da (PCH: Add support for multi architecture iOS
projects, 2020-04-02, v3.18.0-rc1~414^2) we use per-arch .pch files
even when compiling for just the host architecture on macOS arm64.
This breaks with compilers that do not support `-Xarch_` flags, such
as GCC. Avoid using per-arch .pch files in single-architecture builds.
Fixes: #25514
Issue: #20497
In commit cfd8a5ac1f (Makefiles: Add support of DEPFILE for
add_custom_command, 2020-12-04, v3.20.0-rc1~237^2~1) we added a
`ConvertToOutputPath` call on a path given to the `depends` field of
`WriteMakeRule`. The latter already handles escaping for Makefile
syntax.
Fixes: #25554
Makefiles do not have a per-object sense of where they come from, so
forwarding any module information here would end up with incorrect
module file path construction by consuming targets. Leave a TODO item in
its place.
Offer the capability, through variable `CMAKE_LINKER_TYPE`, as well as
the target property `LINKER_TYPE` to specify which linker must be used.
The implementation of this capability is specified by variables specific
to the language and linker type: `CMAKE_<LANG>_USING_LINKER_<TYPE>`.
Some definitions are provided as part of `CMake`.
For example, to select the `LLVM` linker rather than the standard one,
the type `LLD` should be specified through the variable `CMAKE_LINKER_TYPE`.
And, on `Apple`, `Linux` and some environments on `Windows`, the variable
`CMAKE_<LANG>_USING_LINKER_LLD` has value `-fuse-ld=lld`. And for `Windows`
environments based on `MSVC`, where the linker is used directly, the tool
`lld-link.exe` will be used rather than `link.exe`.
Fixes: #19174, #24254, #24990
Now that scanning support is no longer experimental, the logic for
whether or not to scan C++ 20 sources is now important because all
projects are now exposted to the logic. Make the scanning rules explicit
in the documentation and rework the queries to localize all of the
associated logic.
A policy to handle the ultimate fallback logic will be implemented in a
following commit.
571b5e1f2c cxxmodules: improve error messages for C++ module setup
8b4d32c18b cmStandardLevelResolver: add query for the effective standard level
17ddc4ac76 cmStandardLevelResolver: compare with static string literals
6f1dae2b01 cmStandardLevelResolver: use `cmStrCat` where possible
0d45d40e13 cmStandardLevelResolver: use character literals where possible

This handles the case where `COLOR` is set to some ANSI-like color
sequence in the ambient environment. These sequences tend to include `;`
which terminates the command and tries to use the next component
(typically an integer, possibly with a trailing `m`) with errors like:
/bin/sh: line 1: 2: command not found
/bin/sh: line 1: 255: command not found
/bin/sh: line 1: 221: command not found
/bin/sh: line 1: 255m: command not found
Also add a test that sets `COLOR` in the environment which affects the
generated Makefiles behavior.

The `SKIP_LINTING` source property was added to disable code check for
desired source files. The `SKIP_LINTING`includes `cpplint`, `clang-tidy`, \
`cppcheck` and `include-what-you-use`. If `SKIP_LINTING` is set on a
source file, the tools mentioned above will not be run on that source file.
De-duplicate code check rule generation in Ninja and Makefile generators
by moving their implementation to `cmCommonTargetGenerator`.
Previously Ninja was generating code check rules per language.
It was changed to generate code check rules for each source file.
