Cap the number of ELF sections, the section size, and the number of
dynamic entries to reasonable limits for real-world binaries to prevent
OOM on malformed inputs.
Fix commit 615a1c6691 (cmELF: Get correct section count for large ELF
binaries, 2024-02-21, v3.30.0-rc1~354^2) to avoid out-of-bounds access
if both `e_shnum` and the first `sh_size` are zero.

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
Setting `CMAKE_INSTALL_RPATH` on a project that contains statically
linked executables breaks the install step, since rpaths cannot be
changed.
This commit makes rpath adjustments not an error on static libraries.
Fixes#26078
Use ELF headers vendored in `Utilities/cmelf` to get the ELF constants
and types. Using the same ELF definition header for all compilation
targets allows removing some #ifdefs depending on the host OS since we
know all required ELF constants will always be present. To reduce the
size of this commit, the CMake_USE_ELF_PARSER definite will be removed
in a separate commit.
This allows me to use CMAKE_BUILD_WITH_INSTALL_RPATH=False and the Ninja
generator on macOS, whereas before it would always give me the following
error message (despite cross-compiling for an ELF-based platform):
```
The install of the <name> target requires changing an RPATH from
the build tree, but this is not supported with the Ninja generator unless
on an ELF-based platform. The CMAKE_BUILD_WITH_INSTALL_RPATH variable may
be set to avoid this relinking step.
```
DT_MIPS_RLD_MAP_REL is a machine-speicific dynamic tag, so other
architectures could re-use the value of 0x70000035 to mean something
else. Before using DT_MIPS_RLD_MAP_REL, we have to check that the ELF
file is actually has a e_machine of EM_MIPS.
Provide a standardized way to handle the C++ "standard" headers
customized to be used with current CMake C++ standard constraints.
Offer under directory `cm` headers which can be used as direct
replacements of the standard ones. For example:
#include <cm/string_view>
can be used safely for CMake development in place of the `<string_view>`
standard header.
Fixes: #19491
Set the MinTypeNameLength option to an impossibly high value in order
to limit the diagnostics to iterators. Leave new expressions and cast
expressions for later.
An old workaround for `std::allocator_traits<>::value_type` lints from
IWYU on `std::vector<>` usage breaks IWYU's handling of `<memory>`.
Convert the workaround to use the same approach we already use for a
workaround of `std::__decay_and_strip<>::::__type` lints. Then update
the `<memory>` inclusions to follow the now-correct IWYU lints.
Run the `clang-format.bash` script to update all our C and C++ code to a
new style defined by `.clang-format`. Use `clang-format` version 6.0.

We now require C++11 support including `override`. Drop use of
the old compatibility macro. Convert references as follows:
git grep -l CM_OVERRIDE -- '*.h' '*.hxx' '*.cxx' |
xargs sed -i 's/CM_OVERRIDE/override/g'
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.
