With config:
```
AllowShortFunctionsOnASingleLine: Inline
NamespaceIndentation: All
```
The code:
```
namespace Test
{
void f()
{
return;
}
}
```
was incorrectly formatted to:
```
namespace Test
{
void f() { return; }
}
```
since the function `f` was considered being inside a class/struct/record.
That's because the check was simplistic and only checked for a non-zero indentation level of the line starting `f`.

In clang-format 12, `CompactNamespaces` misformatted the code when `AllowShortLambdasOnASingleLine` is set to false and `BraceWrapping.BeforeLambdaBody` is true.
Input:
```
namespace out {
namespace in {
}
} // namespace out::in
```
Expected output:
```
namespace out { namespace in {
}} // namespace out::in
```
Output from v12:
```
namespace out {
namespace in {
}
} // namespace out::in
```
Config triggering the issue:
```
---
AllowShortLambdasOnASingleLine: None
BraceWrapping:
BeforeLambdaBody : true
BreakBeforeBraces: Custom
CompactNamespaces: true
...
```
Seems there's a corner case when `AllowShortLambdasOnASingleLine` is false, and `BraceWrapping.BeforeLambdaBody` is true, that causes CompactNamespaces to stop working.
The cause was a misannotation of `{` opening brace after `namespace` as a lambda opening brace.
The regression was probably introduced with [this commit](fa0118e6e5).

Sorry its taken so long to get to this issue! (got it before it hit its 6th birthday!)
```
void operator delete(void *foo)ATTRIB;
```
(void *foo) is incorrectly determined to be a C-Style Cast resulting in the space being removed after the ) and before the attrib, due to the detection of
```
delete (A* )a;
```
The following was previously unaffected
```
void operator new(void *foo) ATTRIB;
```

There is some similar looking code in `TokenAnnotator.cpp` but given that I've
never worked on clang-format before I don't know what the purpose of that code
is and how it's related to `UnwrappedLineParser.cpp`.
Either way, it fixes clang-format with `BraceWrapping.AfterEnum=true` and
`AllowShortEnumsOnASingleLine=false` to behave like the documentation says.
Before this patch:
```
enum
{
A,
B
} myEnum;
```
After this patch:
```
enum {
A,
B
} myEnum;
```
According to the unittests which I had to modify this would change the LLVM
style. Please evaluate if you want to change the defaults or if you consider
the current style a bug.

It seems that clang-format off/on is not being honoured in regard to adding spaces.
My understanding of clang-format off/on is that it marks the token as finalized based on whether formatting is currently enabled or disabled.
This was causing a space to be added between the `<` and `<<` in the Cuda kernel `foo<<<1, 1>>>();`
This if doesn't solve this actual issue but ensure that clang-format is at least honoured.

Currently, we are unable to inherit from a chain of parent configs where the outermost parent config has `BasedOnStyle: InheritParentConfig` set. This patch adds a test case for this scenario, and adds support for it.
To illustrate, suppose we have the following directory structure:
```
- e/
|- .clang-format (BasedOnStyle: InheritParentConfig) <-- outermost config
|- sub/
|- .clang-format (BasedOnStyle: InheritParentConfig)
|- sub/
|- .clang-format (BasedOnStyle: InheritParentConfig)
|- code.cpp
```
Now consider what happens when we run `clang-format --style=file /e/sub/sub/code.cpp`.
Without this patch, on a release build, only the innermost config will be applied. On a debug build, clang-format crashes due to an assertion failure.
With this patch, clang-format behaves as we'd expect, applying all 3 configs.

Because of the dominance of clang-format in the C++ community, I don't think we should make it the blocker that prevents users from embracing the newer parts of the standard because we butcher the layout of some of the new constucts.

Previously, clang-format would not correctly identify preprocessor
directives directly following a conflict marker, which would result in
violating the formatter's invariants.
The provided test fails in assert mode before this change.
{D110833} regressed behavior of spaces before parentheses for operators, this revision reverts that so that operators are handled as they were before.
I think in hindsight it was a mistake to try and consume operator behaviour in with the function behaviour, I think Operators can be considered a special style. Its seems the code is getting confused as to if this is a function declaration or definition.
I think latterly we can consider adding an operator parentheses specific custom option but this should have been explicitly called out as it can impact projects.

Developers these days seem to argue over east vs west const like they used to argue over tabs vs whitespace or the various bracing style. These previous arguments were mainly eliminated with tools like `clang-format` that allowed those rules to become part of your style guide. Anyone who has been using clang-format in a large team over the last couple of years knows that we don't have those religious arguments any more, and code reviews are more productive.
https://www.youtube.com/watch?v=fv--IKZFVO8https://mariusbancila.ro/blog/2018/11/23/join-the-east-const-revolution/https://www.youtube.com/watch?v=z6s6bacI424
The purpose of this revision is to try to do the same for the East/West const discussion. Move the debate into the style guide and leave it there!
In addition to the new `ConstStyle: Right` or `ConstStyle: Left` there is an additional command-line argument `--const-style=left/right` which would allow an individual developer to switch the source back and forth to their own style for editing, and back to the committed style before commit. (you could imagine an IDE might offer such a switch)
The revision works by implementing a separate pass of the Annotated lines much like the SortIncludes and then create replacements for constant type declarations.
