7a73da4c85 [clang-tidy] Add support for optional parameters in config.
If a parameter value is either 'none', 'null', 'false', '-1'
or '', we will in that case use the default value.

4718da5060 [clang-tidy][NFC] Use C++17 nested namespaces in clang-tidy headers
We forgot to apply the change to headers in the previous patch,
due to missing "-header-filter" in the run-clang-tidy invocation.

2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

4d37af003f [clang-tidy] readability-function-size: add VariableThreshold param.
Summary:
Pretty straight-forward, just count all the variable declarations in the function's body, and if more than the configured threshold - do complain.

Note that this continues perverse practice of disabling the new option by default.
I'm not certain where is the balance point between not being too noisy, and actually enforcing the good practice.
If we really want to not disable this by default, but also to not cause too many new warnings, we could default to 50 or so.
But that is a lot of variables too...

I was able to find one coding style referencing variable count:
  - https://www.kernel.org/doc/html/v4.15/process/coding-style.html#functions

    > Another measure of the function is the number of local variables. They shouldn’t exceed 5-10, or you’re doing something wrong.

a1cee29608 [clang-tidy] readability-function-size: add NestingThreshold param.
Summary:
Finds compound statements which create next nesting level after `NestingThreshold` and emits a warning.
Do note that it warns about each compound statement that breaches the threshold, but not any of it's sub-statements, to have readable warnings.

I was able to find only one coding style referencing nesting:
  - https://www.kernel.org/doc/html/v4.10/process/coding-style.html#indentation
     > In short, 8-char indents make things easier to read, and have the added benefit of warning you when you’re nesting your functions too deep.

This seems too basic, i'm not sure what else to test. Are more tests needed?

9108644dbf [clang-tidy] Add parametercount for readibility-function-size
Summary:
Add an option to function-size to warn about high parameter counts.

This might be relevant for cppcoreguidelines and the safety module as well. Since the safety module is not landed in master already, i did not create an alias, but that can be done later as well.

7663d3be15 Speed up check by using a recursive visitor.
Summary:
Use a recursive visitor instead of forEachDescendant() matcher.
The latter requires several layers of virtual function calls for each node and
it is more expensive than the visitor.
Benchmark results show improvement of ~6% walltime in clang-tidy.

f8ed0a8d35 [clang-tidy] Update docs for clang-tidy checks. NFC
Changes mostly address formatting and unification of the style. Use
MarkDown style for inline code snippets and lists. Added some text
for a few checks.

The idea is to move most of the documentation out to separate rST files and have
implementation files refer to the corresponding documentation files.
