Getting started contributing to Git can be difficult on a Windows
machine. CONTRIBUTING.md contains a guide to getting started, including
detailed steps for setting up build tools, running tests, and
submitting patches to upstream.

The Git for Windows project has grown quite complex over the years,
certainly much more complex than during the first years where the
`msysgit.git` repository was abusing Git for package management purposes
and the `git/git` fork was called `4msysgit.git`.
Let's describe the status quo in a thorough way.

This is the branch thicket of patches in Git for Windows that are
considered ready for upstream. To keep them in a ready-to-submit shape,
they are kept as close to the beginning of the branch thicket as
possible.
It is merely a historical wart that, say, `git-commit` exists in the
`libexec/git-core/` directory, a tribute to the original idea to let Git
be essentially a bunch of Unix shell scripts revolving around very few
"plumbing" (AKA low-level) commands.
Git has evolved a lot from there. These days, most of Git's
functionality is contained within the `git` executable, in the form of
"built-in" commands.
To accommodate for scripts that use the "dashed" form of Git commands,
even today, Git provides hard-links that make the `git` executable
available as, say, `git-commit`, just in case that an old script has not
been updated to invoke `git commit`.
Those hard-links do not come cheap: they take about half a minute for
every build of Git on Windows, they are mistaken for taking up huge
amounts of space by some Windows Explorer versions that do not
understand hard-links, and therefore many a "bug" report had to be
addressed.
The "dashed form" has been officially deprecated in Git version 1.5.4,
which was released on February 2nd, 2008, i.e. a very long time ago.
This deprecation was never finalized by skipping these hard-links, but
we can start the process now, in Git for Windows.
This addresses the concern raised in
https://github.com/git-for-windows/git/pull/4185#discussion_r1051661894
It is checked for w.r.t. global repository struct down in the callstack
in compatibility layer for MinGW before being assigned in the function
that `free()`'d it.
**This requires an ARM64-machine with Windows 11 installed (which
supports x64 emulation for MSYS2)**
### The main idea
- Use the main MSYS2/git-sdk-64 setup, which works on Windows 11 on ARM
thanks to x64-emulation
- Configure the official `clangarm64` MSYS2 repo
- Install `mingw-w64-clang-aarch64-toolchain` which contains the
ARM64-native Clang compiler
Add `FileVersion`, which is a required string ([Microsoft
documentation](https://learn.microsoft.com/en-us/windows/win32/menurc/versioninfo-resource))
in the `StringFileInfo` block.
As not all required strings were present in the block, none were being
included.
Fixes#4090
After including the `FileVersion` string, all other defined strings are
now being included on executables.
File version information for `git.exe` has changed from:

I wasn't really expecting `GIT_VERSION` to contain the Git commit, I was
hoping for just `2.38.1` or `2.38.1.1`, at least for the `FileVersion`
string.
Anybody know if it's possible to concatenate the `MAJOR`, `MINOR`,
`MICRO`, and `PATCHLEVEL` fields with dots, or if there's another
variable that can be used (with or without `PATCHLEVEL`)?
Alternatively, use the complete `GIT_VERSION` for both `FileVersion` and
`ProductVersion`.
Backport a couple fixes to make the CI build run again (so much for
reproducible builds...).

The first three commits are rebased versions of those in gitgitgadget/git#1215. These allow the following:
1. Fix `git config --global foo.bar <path>` from allowing the `<path>`. As a bonus, users with a config value starting with `/` will not get a warning about "old-style" paths needing a "`%(prefix)/`".
2. When in WSL, the path starts with `/` so it needs to be interpolated properly. Update the warning to include `%(prefix)/` to get the right value for WSL users. (This is specifically for using Git for Windows from Git Bash, but in a WSL directory.)
3. When using WSL, the ownership check fails and reports an error message. This is noisy, and happens even if the user has marked the path with `safe.directory`. Remove that error message.
This merges the current version of the patch that tries to address Git
GUI's problems with intent-to-add files.
This patch will likely be improved substantially before it is merged
into Git GUI's main branch, but we want to have _something_ resembling a
fix already in Git for Windows v2.29.0.

This topic branch allows `add -p` and `add -i` with a large number of
files. It is kind of a hack that was never really meant to be
upstreamed. Let's see if we can do better in the built-in `add -p`.

In f9b7573f6b (repository: free fields before overwriting them,
2017-09-05), Git was taught to release memory before overwriting it, but
357a03ebe9 (repository.c: move env-related setup code back to
environment.c, 2018-03-03) changed the code so that it would not
_always_ be overwritten.
As a consequence, the `commondir` attribute would point to
already-free()d memory.
This seems not to cause problems in core Git, but there are add-on
patches in Git for Windows where the `commondir` attribute is
subsequently used and causing invalid memory accesses e.g. in setups
containing old-style submodules (i.e. the ones with a `.git` directory
within theirs worktrees) that have `commondir` configured.
This fixes https://github.com/git-for-windows/git/pull/4083.

No GitHub-hosted ARM64 runners are available at the moment of writing,
but folks can leverage self-hosted runners of this architecture. This CI
pipeline comes in handy for forks of the git-for-windows/git project
that have such runners available. The pipeline can be kicked off
manually through a workflow_dispatch.
