git often requests `strbuf_realpath(path + "/.git")`, where "./git" does
not yet exist on disk.
This causes the following to happen:
1. `mingw_strbuf_realpath()` fails
2. Non-mingw `strbuf_realpath()` does the work
3. Result of `strbuf_realpath()` is slightly different, for example it
will not normalize the case of disk/folder names
4. `needs_work_tree_config()` becomes confused by these differences
5. clone adds `core.worktree` setting
This in turn causes various problems, for example:
1. Repository folder can no longer be renamed/moved without breaking it
2. Using the repository on WSL (Windows Subsystem for Linux) doesn't
work, because it has windows-style path saved

This change enhances `git commit --cleanup=scissors` by detecting
scissors lines ending in either LF (UNIX-style) or CR/LF (DOS-style).
Regression tests are included to specifically test for trailing
comments after a CR/LF-terminated scissors line.

As of Git for Windows v2.27.0, there is an option to use Windows'
newly-introduced Pseudo Console support. When running an interactive add
operation with this support enabled, Git will receive CR/LF line
endings.
Therefore, let's not pretend that we are expecting Unix line endings.

In https://github.com/git-for-windows/git/pull/2637, we fixed a bug
where symbolic links' target path sizes were recorded incorrectly in the
index.
However, we did so only in `mingw_lstat()` but not in `fscache_lstat()`.
Meaning: in code paths where the FSCache feature is enabled, Git _still_
got the wrong idea if the symbolic link target's length.
Let's fix this.
Note: as the FSCache feature reads in whole swaths of directory entries
in batch mode, even if metadata for only one of them might be required,
we save the expensive `CreateFile()` call that is required to compute
the symbolic link target's length to the `fscache_lstat()` call.
This fixes https://github.com/git-for-windows/git/issues/2653.

In https://github.com/git-for-windows/git/pull/2637, we fixed a bug
where symbolic links' target path sizes were recorded incorrectly in the
index. The downside of this fix was that every user with tracked
symbolic links in their checkouts would see them as modified in `git
status`, but not in `git diff`, and only a `git add <path>` (or `git add
-u`) would "fix" this.
Let's do better than that: we can detect that situation and simply
pretend that a symbolic link with a known bad size (or a size that just
happens to be that bad size, a _very_ unlikely scenario because it would
overflow our buffers due to the trailing NUL byte) means that it needs
to be re-checked as if we had just checked it out.

This topic branch re-adds the deprecated --stdin/-z options to `git
reset`. Those patches were overridden by a different set of options in
the upstream Git project before we could propose `--stdin`.
We offered this in MinGit to applications that wanted a safer way to
pass lots of pathspecs to Git, and these applications will need to be
adjusted.
Instead of `--stdin`, `--pathspec-from-file=-` should be used, and
instead of `-z`, `--pathspec-file-nul`.

This branch allows third-party tools to call `git status
--no-lock-index` to avoid lock contention with the interactive Git usage
of the actual human user.

We already avoid traversing NTFS junction points in `git clean -dfx`.
With this topic branch, we do that when the FSCache is enabled, too.

When updating the skip-worktree bits in the index to align with new
values in a sparse-checkout file, Git scans the entire working
directory with lstat() calls. In a sparse-checkout, many of these
lstat() calls are for paths that do not exist.
Enable the fscache feature during this scan.
In a local test of a repo with ~2.2 million paths, updating the index
with `git read-tree -m -u HEAD` with a sparse-checkout file containing
only `/.gitattributes` improved from 2-3 minutes to 15-20 seconds.
More work could be done to stop running lstat() calls when recursing
into directories that are known to not exist.
This brings substantial wins in performance because the FSCache is now
per-thread, being merged to the primary thread only at the end, so we do
not have to lock (except while merging).

The `--stdin` option was a well-established paradigm in other commands,
therefore we implemented it in `git reset` for use by Visual Studio.
Unfortunately, upstream Git decided that it is time to introduce
`--pathspec-from-file` instead.
To keep backwards-compatibility for some grace period, we therefore
reinstate the `--stdin` option on top of the `--pathspec-from-file`
option, but mark it firmly as deprecated.

The option is deprecated now, and we better make sure that keeps saying
so until we finally remove it.

This topic branch allows `add -p` and `add -i` with a large number of

It was a bad idea to just remove that option from Git for Windows
v2.15.0, as early users of that (still experimental) option would have
been puzzled what they are supposed to do now.
So let's reintroduce the flag, but make sure to show the user good
advice how to fix this going forward.
We'll remove this option in a more orderly fashion either in v2.16.0 or
in v2.17.0.

These are Git for Windows' Git GUI and gitk patches. We will have to
decide at some point what to do about them, but that's a little lower
priority (as Git GUI seems to be unmaintained for the time being, and
the gitk maintainer keeps a very low profile on the Git mailing list,
too).
