The ORIG_HEAD pseudo ref is supposed to refer to the original,
pre-rebase state after a successful rebase. Let's add a regression test
to prove that this regressed: With GIT_TEST_REBASE_USE_BUILTIN=false,
this test case passes, with GIT_TEST_REBASE_USE_BUILTIN=true (or unset),
it fails.

In the case that the rebase boils down to a fast-forward, the built-in
rebase reset the working tree twice: once to start the rebase at `onto`,
then realizing that the original (pre-rebase) HEAD was an ancestor and
we basically already fast-forwarded to the post-rebase HEAD,
`reset_head()` was called to update the original ref and to point HEAD
back to it.
That second `reset_head()` call does not need to touch the working tree,
though, as it does not change the actual tip commit (and therefore the
working tree should stay unchanged anyway): only the ref needs to be
updated (because the rebase detached the HEAD, and we want to go back to
the branch on which the rebase was started).
But that second `reset_head()` was called without the flag to leave the
working tree alone (the reason: when that call was introduced, that flag
was not yet even thought of). Let's avoid that unnecessary work by
passing that flag.

In 1cadad6f65 (git clone <url> C:\cygwin\home\USER\repo' is working
(again), 2018-12-15), we introduced a new source file, containing
utility functions on Windows. But we forgot to adjust the MSVC section.

On Windows, symbolic links have a type: a "file symlink" must point at
a file, and a "directory symlink" must point at a directory. If the
type of symlink does not match its target, it doesn't work.
Git does not record the type of symlink in the index or in a tree. On
checkout it'll guess the type, which only works if the target exists
at the time the symlink is created. This may often not be the case,
for example when the link points at a directory inside a submodule.
By specifying `symlink=file` or `symlink=dir` the user can specify what
type of symlink Git should create, so Git doesn't have to rely on
unreliable heuristics.

This drops the patch that made it already upstream (and Git for Windows
added the line *another* time)...

On Windows, symbolic links actually have a type depending on the target:
it can be a file or a directory.
In certain circumstances, this poses problems, e.g. when a symbolic link
is supposed to point into a submodule that is not checked out, so there
is no way for Git to auto-detect the type.
To help with that, we will add support over the course of the next
commits to specify that symlink type via the Git attributes. This
requires an index_state, though, something that Git for Windows'
`symlink()` replacement cannot know about because the function signature
is defined by the POSIX standard and not ours to change.
So let's introduce a helper function to create symbolic links that
*does* know about the index_state.

Since `git_check_attr()` implicitly depends on the index, we really
should redo this in a manner that has a chance of going into upstream:
by introducing an index-aware helper function to create symbolic links,
and to override that in a Windows-specific manner instead.
In preparation for this, let's drop the original commit for now.

This branch allows third-party tools to call `git status

To avoid having to play tricks as in earlier rounds, we bit the sour
apple and rebased the `builtin-stash-rebase-v3` branch thicket onto the
commit starting Git for Windows' merging-rebase.
(The merging-rebase pulls in the previous branch thicket via a "fake
merge", i.e. a merge commit that does not actually apply any changes
from the merged commit history. This has the unfortunate side effect of
confusing `merge` into thinking that any branch that was merged into an
earlier round does not need to be merged again.)

This fixes the issue identified in
https://github.com/git-for-windows/git/issues/1498
where Git would not fall back to reading credentials from a Win32
Console when the credentials could not be read from the terminal via the
Bash hack (that is necessary to support running in a MinTTY).
Tested in a Powershell window.

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).

Git for Windows supports the core.longPaths config setting to allow
writing/reading long paths via the \\?\ trick for a long time now.
However, for that support to work, it is absolutely necessary that
git_default_config() is given a chance to parse the config. Otherwise
Git will be non the wiser.
So let's make sure that as many commands that previously failed to
parse the core.* settings now do that, implicitly enabling long path
support in a lot more places.
Note: this is not a perfect solution, and it cannot be, as there is
a chicken-and-egg problem in reading the config itself...

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).
