`Shutdown.h` was transitively depending on two headers, but this isn't
allowed under a modules build, so they're now explicitly included.

The purpose of the `FileNotFound` preprocessor callback was to add the ability to recover from failed header lookups. This was to support downstream project.
However, injecting additional search path while performing header search can invalidate currently used iterators/references to `DirectoryLookup` in `Preprocessor` and `HeaderSearch`.
The downstream project ended up maintaining a separate patch to further tweak the functionality. Since we don't have any upstream users nor open source downstream users, I'd like to remove this callback for good to prevent future misuse. I doubt there are any actual downstream users, since the functionality is definitely broken at the moment.

The pointer is referenced immediately, so assert the cast is correct instead of returning nullptr
It's only later iterations of the loop where the getParent() call might return nullptr
... if there is a match.
This is needed to that clients can can make a connection between a
diagnostic and an associated quickfix-tweak.
Ideally, quickfix-kind tweak code actions would be provided inline along
with the non-tweak fixes, but this doesn't seem easily achievable.

This option allows callers to disable the warning from
https://clang.llvm.org/extra/clang-tidy/checks/performance-move-const-arg.html
that would warn on the following
```
void f(const string &s);
string s;
f(std::move(s)); // ALLOWED if performance-move-const-arg.CheckMoveToConstRef=false
```
The reason people might want to disable this check, is because it allows
callers to use `std::move()` or not based on local reasoning about the
argument, and without having to care about how the function `f` accepts
the argument. Indeed, `f` might accept the argument by const-ref today,
but change to by-value tomorrow, and if the caller had moved the
argument that they were finished with, the code would work as
efficiently as possible regardless of how `f` accepted the parameter.

Ensure CLANG_PLUGIN_SUPPORT is compatible with llvm_add_library.

This will allow moving the IncludeCleaner library essentials to Clang
and decoupling them from the majority of clangd.
The patch itself just moves the code, it doesn't change existing

Implement P2128R6 in C++23 mode.
Unlike GCC's implementation, this doesn't try to recover when a user
meant to use a comma expression.
Because the syntax changes meaning in C++23, the patch is *NOT*
implemented as an extension. Instead, declaring an array with not
exactly 1 parameter is an error in older languages modes. There is an
off-by-default extension warning in C++23 mode.
Unlike the standard, we supports default arguments;
Ie, we assume, based on conversations in WG21, that the proposed
resolution to CWG2507 will be accepted.
We allow arrays OpenMP sections and C++23 multidimensional array to
coexist:
[a , b] multi dimensional array
[a : b] open mp section
[a, b: c] // error
The rest of the patch is relatively straight forward: we take care to
support an arbitrary number of arguments everywhere.
The test invocation at the start of run-clang-tidy.py (line 257) prints
all enabled checks - meaning either the default set or anything
configured via the -checks option. If any checks were (un-)configured
via the -config option, these are not printed. This is confusing to the
user, since the list of checks that are printed may be different from
the list of checks that are used by the non-testing calls to clang-tidy,
where the -config option is passed correctly.
This patch adds the -config option to the test invocation of clang-tidy
at the start of the script. This means that checks (un-)configured via
the -config option (rather than the -checks option) are applied
correctly, when printing the list of enabled checks.
With this change, clangd now computes framework-style includes
for framework headers at indexing time.

There were some left-overs (or new things) from the previous patches.
This will get us down to 0 open findings except:
clang-tidy is complaining in some files about
`warning: #includes are not sorted properly [llvm-include-order]`
however, clang-format does revert these changes.
It looks like clang-tidy and clang-format disagree there.
Not sure how we can fix that...

It also hides warnings about pre-releases when the git suffix

Auto-generated patch based on clang-tidy readability-identifier-naming.
Only some manual cleanup for `extern "C"` declarations and a GTest change was required.
I'm not sure if this cleanup is actually very useful. It cleans up clang-tidy findings to the number of warnings from clang-tidy should be lower. Since it was easy to do and required only little cleanup I thought I'd upload it for discussion.
One pattern that keeps recurring: Test **matchers** are also supposed to start with a lowercase letter as per LLVM convention. However GTest naming convention for matchers start with upper case. I would propose to keep stay consistent with the GTest convention there. However that would imply a lot of `//NOLINT` throughout these files.
To re-product this patch run:
```
run-clang-tidy -checks="-*,readability-identifier-naming" -fix -format ./clang-tools-extra/clangd
```
To convert the macro names, I was using this script with some manual cleanup afterwards:

Display notes for a possible call chain if an unsafe function is found to be
called (maybe indirectly) from a signal handler.
The call chain displayed this way includes probably not the first calls of
the functions, but it is a valid possible (in non path-sensitive way) one.

Inside a switch the caseStmt() and defaultStmt() have a nested statement
associated with them. Similarly, labelStmt() has a nested statement.
These statements were being missed when looking for a compound-if of the
form "if (x) return true; return false;" when the if is nested under one
of these labelling constructs.
Enhance the matchers to look for these nested statements using some
private matcher hasSubstatement() traversal matcher on case, default
and label statements. Add the private matcher hasSubstatementSequence()
to match the compound "if (x) return true; return false;" pattern.
- Add unit tests for private matchers and corresponding test
infrastructure
- Add corresponding test file readability-simplify-bool-expr-case.cpp.
- Fix variable name copy/paste error in readability-simplify-bool-expr.cpp.
- Drop the asserts, which were used only for debugging matchers.
- Run clang-format on the whole check.
- Move local functions out of anonymous namespace and declare state, per
LLVM style guide
- Declare labels constexpr
- Declare visitor arguments as pointer to const
- Drop braces around simple control statements per LLVM style guide
- Prefer explicit arguments over default arguments to methods
