A common source of security bugs is code that opens a file descriptors without using the O_CLOEXEC flag. (Without that flag, an opened sensitive file would remain open across a fork+exec to a lower-privileged SELinux domain, leaking that sensitive data.).

Summary:
A followup for D32942.
Malcolm Parsons has provided a valid testcase that the initial version of the check complained about nested `if`'s.
As it turns out, the culprit is the **partially** un-intentional `switch` fallthrough.
So rewrite the NestingThreshold logic without ab-using+mis-using that switch with fallthrough, and add testcases with nested `if`' where there should be a warning and shouldn't be a warning. This results in a cleaner, simpler code, too.
I guess, now it would be actually possible to pick some reasonable default for `NestingThreshold` setting.
Fixes PR33454.

Summary:
The goal of this change is to fix the following suboptimal replacements currently suggested by clang-tidy:
```
// with MemberPrefix == "_"
int __foo; // accepted without complaint
```
```
// with MemberPrefix == "m_"
int _foo;
^~~~~~
m__foo
```
I fixed this by
- updating `matchesStyle()` to reject names which have a leading underscore after a prefix has already been stripped, or a trailing underscore if a suffix has already been stripped;
- updating `fixupWithStyle()` to strip leading & trailing underscores before adding the user-defined prefix and suffix.
The replacements are now:
```
// MemberPrefix == "_"
int __foo;
^~~~~~
_foo
```
```
// MemberPrefix == "m_"
int _foo;
^~~~~
m_foo
```
Future improvements might elect to add .clang-tidy flags to improve what is being stripped. For instance, stripping `m_` could allow `m_foo` to be automatically replaced with `_foo`.

ADL as reasonable extension points.
All of this would be cleaner if this code followed the more usual LLVM
convention of not having deeply nested namespaces inside of .cpp files
and instead having a `using namespace ...;` at the top. Then the static
function would be in the global namespace and easily referred to as
`::join`. Instead we have to write a fairly contrived qualified name.
I figure the authors can clean this up with a less ambiguous name, using
the newly provided LLVM `join` function, or any other solution, but this
at least fixes the build.

The check doesn't really know if the code it is warning about came before
or after the header guard, so phrase it more neutral instead of complaining
about code before the header guard. The location for the warning is still
not optimal, but I don't think fixing that is worth the effort, the
preprocessor doesn't give us a better location.

Summary:
This flag allows specifying a custom path for the compilation
database. Unfortunately we can't use the -p flag like other
clang-tidy tools because it's already taken.

Summary:
Replaces explicit calls to the constructor in a return with a braced
initializer list. This way the return type is not needlessly duplicated in the
return type and the return statement.
```
Foo bar() {
Baz baz;
return Foo(baz);
}
// transforms to:
Foo bar() {
Baz baz;
return {baz};
}
```

Summary:
The misc-unconventional-assign-operator check had a false positive
warning when the 'operator*' in 'return *this' was unresolved.
Change matcher to allow calls to unresolved operator.
Fixes PR31531.

Summary:
Users might get confused easily when they see the check's message on
full template function speciliations.
Add a note to the output message, which mentions these kind of function
specializations are treated as regular functions.

I have made a small fix for readability-delete-null-pointer check so it also checks for class members.
Example of case that it fixes
```
struct A {
void foo() {
if(mp)
delete mp;
}
int *mp;
};
```

Summary:
This new flag instructs clang-tidy to not output anything
except for errors and warnings. This makes it easier to
script clang-tidy to run as part of external build systems.

Now for real. The use case supported previously is used by approximately nobody.
What's needed is support for matching argument comments in EXPECT_xxx calls to
the names of parameters of the mocked methods.

Fixes PR30964. The old behavior can be achieved using a setting.

Summary:
The performance-unnecessary-value-param check mangled inherited
constructors, as the constructors' parameters do not have useful source
locations. Fix this by ignoring implicit functions.
Fixes PR31684.
