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.
Even if CMake is not the canonical way to build Git for Windows, but
CMake support merely exists in Git to support building Git for Windows
using Visual Studio, we should include `headless-git` in such a scenario
when installing the binaries to a given location.
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`.

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.

When the `vcxproj` target was introduced in `config.mak.uname` to allow
building Git with the Visual C toolchain, the `git remote-ext` command
was always executed in its dashed form. Therefore, it was impossible to
pass the test suite unless that command existed in its dashed form, and
we had to special-case this.
Later, when the `vcxproj` target got out of fashion because Visual
Studio gained native support for CMake builds, this special-casing was
copied without questioning it.
But as of 675df192c5 (transport-helper: do not run git-remote-ext etc.
in dashed form, 2020-08-26), the reason for this special-casing no
longer exists. So let's just drop it.

In ccfba9e0c4 (Makefile: use "generate-perl.sh" to massage Perl
library, 2024-12-06), the previous strategy (which avoided spawning a
shell script to transform the files) was replaced by the same
`generate-perl.sh` invocation as for the Makefile-based build.
The only difference is that now the transformation tries to handle the
Perl modules in-place (which ends up in empty files because the same
file is used as input and output via stdin/stdout redirection), and the
Perl script cannot find them anymore because they are not in the
expected place.
Let's put them into the expected place again, i.e. into
`perl/build/lib/` instead of `perl/`.

In e4b488049a (Makefile: extract script to massage Perl scripts,
2024-12-06), the code was refactored that is used to transform the Perl
scripts/modules to their final form.
Even the CMake-based build was adjusted, but the change used the file
name `PERL-HEADER` instead of the file name used by the Makefile-based
build (same name but with the `GIT-` prefix). Let's adjust the former to
the latter.

In 7e0730c8ba (t: better support for out-of-tree builds, 2024-12-06)
the strategy was changed from letting `t7609-mergetool--lib.sh`
hard-code the directory where it expects to find the merge tools to
hard-coding that value in the placeholder `@GIT_TEST_MERGE_TOOLS_DIR@`
that is replaced during the build.
However, likely due to a copy/paste mistake (and reviewers missed this,
too), the CMake-based build was adjusted incorrectly, replacing that
placeholder not with the path to the merge tools, but with a Boolean
indicating whether to use a runtime-generated path prefix or not.
Let's fix that, addressing this CMake-build's symptom:
Initialized empty Git repository in D:/a/git/git/t/trash directory.t7609-mergetool--lib/.git/
++ . true/vimdiff
./test-lib.sh: line 1021: true/vimdiff: No such file or directory

In 7e0730c8ba (t: better support for out-of-tree builds, 2024-12-06),
the `bin-wrappers/` strategy was changed so that it no longer hard-codes
the template directory to be `@BUILD_DIR@/templates/blt`, but instead
interpolates the `@TEMPLATE_DIR@` placeholder during the build.
However, this commit only adjusted the `Makefile`-based build.
Let's adjust the CMake-based build as well. This fixes t0000.15 which
would otherwise fail with:

This fixes a bug in the implementation of `ps/mingw-rename` that
prevented directories from being handled by the POSIX-compliant
`SetFileInformationByHandle()` code path.

In 391bceae43 (compat/mingw: support POSIX semantics for atomic
renames, 2024-10-27), we taught the `mingw_rename()` function to respect
POSIX semantics, but we did so only as a fallback after `_wrename()`
fails.
This hid a bug in the implementation that was not caught by Git's test
suite: The `CreateFileW()` function _can_ open handles to directories,
but not when asked to use the `FILE_ATTRIBUTE_NORMAL` flag, as that flag
only is allowed for files.
Let's fix this by using the common `FILE_FLAG_BACKUP_SEMANTICS` flag
that can be used for opening handles to directories, too.

As reported in https://lore.kernel.org/git/ZuPKvYP9ZZ2mhb4m@pks.im/,
libcurl v8.10.0 had a regression that was picked up by Git's t5559.30
"large fetch-pack requests can be sent using chunked encoding".
This bug was fixed in libcurl v8.10.1.
Sadly, the macos-13 runner image was updated in the brief window between
these two libcurl versions, breaking each and every CI build, as
reported at https://github.com/git-for-windows/git/issues/5159.
This would usually not matter, we would just ignore the failing CI
builds until the macos-13 runner image is rebuilt in a couple of days,
and then the CI builds would succeed again.
However.
As has become the custom, a surprise Git version was released, and now
that Git for Windows wants to follow suit, since Git for Windows has
this custom of trying to never release a version with a failing CI
build, we _must_ work around it.
This patch implements this work-around, basically for the sake of Git
for Windows v2.46.2's CI build.

From the documentation of said setting:
This boolean will enable fsync() when writing object files.
This is a total waste of time and effort on a filesystem that
orders data writes properly, but can be useful for filesystems
that do not use journalling (traditional UNIX filesystems) or
that only journal metadata and not file contents (OS X’s HFS+,
or Linux ext3 with "data=writeback").
The most common file system on Windows (NTFS) does not guarantee that
order, therefore a sudden loss of power (or any other event causing an
unclean shutdown) would cause corrupt files (i.e. files filled with
NULs). Therefore we need to change the default.
Note that the documentation makes it sound as if this causes really bad
performance. In reality, writing loose objects is something that is done
only rarely, and only a handful of files at a time.

NtQueryObject under Wine can return a success but fill out no name.
In those situations, Wine will set Buffer to NULL, and set result to
the sizeof(OBJECT_NAME_INFORMATION).
Running a command such as
echo "$(git.exe --version 2>/dev/null)"
will crash due to a NULL pointer dereference when the code attempts to
null terminate the buffer, although, weirdly, removing the subshell or
redirecting stdout to a file will not trigger the crash.
Code has been added to also check Buffer and Length to ensure the check
is as robust as possible due to the current behavior being fragile at
best, and could potentially change in the future
This code is based on the behavior of NtQueryObject under wine and
reactos.

For Windows builds >= 15063 set $env:TERM to "xterm-256color" instead of
"cygwin" because they have a more capable console system that supports
this. Also set $env:COLORTERM="truecolor" if unset.
$env:TERM is initialized so that ANSI colors in color.c work, see
29a3963484 (Win32: patch Windows environment on startup, 2012-01-15).
See git-for-windows/git#3629 regarding problems caused by always setting
$env:TERM="cygwin".
