Emulating the POSIX lstat API on Windows via GetFileAttributes[Ex] is quite
slow. Windows operating system APIs seem to be much better at scanning the
status of entire directories than checking single files. A caching
implementation may improve performance by bulk-reading entire directories
or reusing data obtained via opendir / readdir.
Make the lstat implementation pluggable so that it can be switched at
runtime, e.g. based on a config option.

Emulating the POSIX `dirent` API on Windows via
`FindFirstFile()`/`FindNextFile()` is pretty staightforward, however,
most of the information provided in the `WIN32_FIND_DATA` structure is
thrown away in the process. A more sophisticated implementation may
cache this data, e.g. for later reuse in calls to `lstat()`.
Make the `dirent` implementation pluggable so that it can be switched at
runtime, e.g. based on a config option.
Define a base DIR structure with pointers to `readdir()`/`closedir()`
that match the `opendir()` implementation (similar to vtable pointers in
Object-Oriented Programming). Define `readdir()`/`closedir()` so that
they call the function pointers in the `DIR` structure. This allows to
choose the `opendir()` implementation on a call-by-call basis.
Make the fixed-size `dirent.d_name` buffer a flex array, as `d_name` may
be implementation specific (e.g. a caching implementation may allocate a
`struct dirent` with _just_ the size needed to hold the `d_name` in
question).

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 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

This topic branch allows us to specify absolute paths without the drive
prefix e.g. when cloning.
Example:
C:\Users\me> git clone https://github.com/git/git \upstream-git
This will clone into a new directory C:\upstream-git, in line with how
Windows interprets absolute paths.

These fixes were necessary for Sverre Rabbelier's remote-hg to work,
but for some magic reason they are not necessary for the current
