After https://reviews.llvm.org/D151954 we've noticed some issues w/
clang-format behavior, as outlined in
https://github.com/llvm/llvm-project/issues/63170.
Valid C/C++ files, that were previously accepted, are now rejected by
clang-format, emitting the message:
"The new replacement overlaps with an existing replacement."
This reverts commit 4b9764959dc4b8783e18747c1742ab164e4bc4ee and
d2627cf88d2553a4c2e850430bdb908a4b7d2e52, which depends on it.

Adds an option KeepEmptyLinesAtEOF to keep empty lines (up to
MaxEmptyLinesToKeep) before EOF. This remedies the probably unintentional
change in behavior introduced in 3d3ea84a4f8f, which started to always
remove empty lines before EOF.
Fixes#56054.
Fixes#63150.

This adds to the ObjC language guesser a few more common macros used
in ObjC headers. These can help distinguish ObjC headers which
otherwise lack ObjC types from C++ headers.

This patch migrates uses of StringRef::{starts,ends}with_insensitive
to StringRef::{starts,ends}_with_insensitive so that we can use names
similar to those used in std::string_view.
Note that the llvm/ directory has migrated in commit
6c3ea866e93003e16fc55d3b5cedd3bc371d1fde.
I'll post a separate patch to deprecate
StringRef::{starts,ends}with_insensitive.

This patch uses original code but with an init capture that does a move instead of a copy.

Add configuration to specify macros.
Macros will be expanded, and the code will be parsed and annotated
in the expanded state. In a second step, the formatting decisions
in the annotated expanded code will be reconstructed onto the
original unexpanded macro call.
Eventually, this will allow to remove special-case code for
various macro options we accumulated over the years in favor of
one principled mechanism.

This reverts commit 879bfe6a979295f834b76df66b19a203b93eed0f.
owenpan@ pointed out on https://reviews.llvm.org/D140956 that this
actually makes the formatting more consistent, so it's not a regression.
This reverts commit a28f0747c2f3728bd8a6f64f7c8ba80b4e0cda9f.
It appears that this regresses some function definitions, added an
example as a comment over at https://reviews.llvm.org/D140956.

This patch mechanically replaces None with std::nullopt where the
compiler would warn if None were deprecated. The intent is to reduce
the amount of manual work required in migrating from Optional to
std::optional.
This is part of an effort to migrate from llvm::Optional to
std::optional:

This adds command-line flags to the tool:
+ -print: prints changed source code
+ -print=changes: prints headers added/removed
+ -edit: rewrites code in place
+ -insert=0/-remove=0: disables additions/deletions for the above
These are supported by a couple of new functions dumped into Analysis:
analyze() sits on top of walkUsed and makes used/unused decisions for
Includes. fixIncludes() applies those results to source code.

I've:
- Sorted the members of FormatStyle alphabetical. The enums and structs
are kept close to the member.
- Sorted the yaml io functions, based on the type they operate on.
- Sorted the initializers in getLLVMStyle(), except that penalities are
kept at the end.
- Sorted the io of FormatStyle, this changes the --dump-config behavior.
- Moved the deprecated options into the only input case, this also
changes --dump-config, it does not put the not directly used options
in the .clang-format anymore.
- Sorted the comparisons in operator==.
- Added WhiteSpaceMacros in operator==, I've not actively looked if all
other members are compared.
- This showed flawed tests (or in my opinion a flawed io operation, but
that is another discussion and change).

Working in a mixed environment of both vscode/vim with a team configured prettier configuration, this can leave clang-format and prettier fighting each other over the formatting of arrays, both simple arrays of elements.
This review aims to add some "control knobs" to the Json formatting in clang-format to help align the two tools so they can be used interchangeably.
This will allow simply arrays `[1, 2, 3]` to remain on a single line but will break those arrays based on context within that array.
Happy to change the name of the option (this is the third name I tried)
