Currently the lambda body indents relative to where the lambda signature is located. This instead lets the user
choose to align the lambda body relative to the parent scope that contains the lambda declaration. Thus:
someFunction([] {
lambdaBody();
});
will always have the same indentation of the body even when the lambda signature goes on a new line:
someFunction(
[] {
lambdaBody();
});
whereas before lambdaBody would be indented 6 spaces.

This allows to set a different indent width for preprocessor statements.

The current logic for access modifiers in classes ignores the option 'MaxEmptyLinesToKeep=1'. It is therefore impossible to have a coding style that requests one empty line after an access modifier. The patch allows the user to configure how many empty lines clang-format should add after an access modifier. This will remove lines if there are to many and will add them if there are missing.

This commit removes the old way of handling Whitesmiths mode in favor of just setting the
levels during parsing and letting the formatter handle it from there. It requires a bit of
special-casing during the parsing, but ends up a bit cleaner than before. It also removes
some of switch/case unit tests that don't really make much sense when dealing with
Whitesmiths.

Adds support for coding styles that make a separate indentation level for access modifiers, such as Code::Blocks or QtCreator.
The new option, `IndentAccessModifiers`, if enabled, forces the content inside classes, structs and unions (“records”) to be indented twice while removing a level for access modifiers. The value of `AccessModifierOffset` is disregarded in this case, aiming towards an ease of use.

Q_FOREACH(int a; list)

foo();

Q_FOREACH(int longVariable;

This patch fixes bug #44192
When clang-format is run with option AllowShortBlocksOnASingleLine, it is expected to either succeed in putting the short block with its control statement on a single line or fail and leave the block as is. When brace wrapping after control statement is activated, if the block + the control statement length is superior to column limit but the block alone is not, clang-format puts the block in two lines: one for the control statement and one for the block. This patch removes this unexpected behaviour. Current unittests are updated to check for this behaviour.

Summary:
Change the BraceWrappingFlags' AfterControlStatement from a bool to an enum with three values:
* "Never": This is the default, and does not do any brace wrapping after control statements.
* "MultiLine": This only wraps braces after multi-line control statements (this really only happens when a ColumnLimit is specified).
* "Always": This always wraps braces after control statements.
The first and last options are backwards-compatible with "false" and "true", respectively.
The new "MultiLine" option is useful for when a wrapped control statement's indentation matches the subsequent block's indentation. It makes it easier to see at a glance where the control statement ends and where the block's code begins. For example:
```
if (
foo
&& bar )
{
baz();
}
```
vs.
```
if (
foo
&& bar ) {
baz();
}
```
Short control statements (1 line) do not wrap the brace to the next line, e.g.
```
if (foo) {
bar();
} else {
baz();
}
```

This patch deals with this cases by introducing a new option to specify

Summary:
This revision adds basic support for formatting C# files with clang-format, I know the barrier to entry is high here so I'm sending this revision in to test the water as to whether this might be something we'd consider landing.
Tracking in Bugzilla as:
https://bugs.llvm.org/show_bug.cgi?id=40850
Justification:
C# code just looks ugly in comparison to the C++ code in our source tree which is clang-formatted.
I've struggled with Visual Studio reformatting to get a clean and consistent style, I want to format our C# code on saving like I do now for C++ and i want it to have the same style as defined in our .clang-format file, so it consistent as it can be with C++. (Braces/Breaking/Spaces/Indent etc..)
Using clang format without this patch leaves the code in a bad state, sometimes when the BreakStringLiterals is set, it fails to compile.
Mostly the C# is similar to Java, except instead of JavaAnnotations I try to reuse the TT_AttributeSquare.
Almost the most valuable portion is to have a new Language in order to partition the configuration for C# within a common .clang-format file, with the auto detection on the .cs extension. But there are other C# specific styles that could be added later if this is accepted. in particular how `{ set;get }` is formatted.

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

Summary:
This is done in order to improve cases where the lambda's body is moved too far to the right. Consider the following snippet with column limit set to 79:
```
void f() {
leader::MakeThisCallHere(&leader_service_,
cq_.get(),
[this, liveness](const leader::ReadRecordReq& req,
std::function<void()> done) {
logger_->HandleReadRecord(
req, resp, std::move(done));
});
leader::MakeAnother(&leader_service_,
cq_.get(),
[this, liveness](const leader::ReadRecordReq& req,
std::function<void()> done) {
logger_->HandleReadRecord(
req, resp, std::move(done), a);
});
}
```
The tool favors extra indentation for the lambda body and so the code incurs extra wrapping and adjacent calls are indented to a different level. I find this behavior annoying and I'd like the tool to favor new lines and, thus, use the extra width.
The fix, reduced, brings the following formatting.
Before:
function(1,
[] {
DoStuff();
//
},
1);
After:
function(
1,
[] {
DoStuff();
//
},
1);

This change fixes namespaces not being identified as such with preceding 'inline' or 'export' specifiers.
Motivation: I was experimenting with the Modules TS (-fmodules-ts) and found it would be useful if clang-format would correctly format 'export namespace'. While making the changes, I noticed that similar issues still exist with 'inline namespace', and addressed them as well.

This required a couple of yaks to be shaved:
1. MatchingOpeningBlockLineIndex was misused to also store the
closing index; instead, use a second variable, as this doesn't
work correctly for "} else {".
2. We needed to change the API of AffectedRangeManager to not
use iterators; we always passed in begin / end for the whole
container before, so there was no mismatch in generality.
3. We need an extra check to discontinue formatting at the top
level, as we now sometimes change the indent of the closing
brace, but want to bail out immediately afterwards, for
example:
void f() {
if (a) {
}
void g();
Previously:
void f() {
