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.)

For many Win32 functions, there actually exist two variants: one with
the `A` suffix that takes ANSI parameters (`char *` or `const char *`)
and one with the `W` suffix that takes Unicode parameters (`wchar_t *`
or `const wchar_t *`).
Let's be precise what we want to use.

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...

This branch introduces support for reading the "Windows-wide" Git
configuration from `%PROGRAMDATA%\Git\config`. As these settings are
intended to be shared between *all* Git-related software, that config
file takes an even lower precedence than `$(prefix)/etc/gitconfig`.

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).

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.
This branch adds back the scripted versions, then adds the option to
use the builtin versions of `stash` and `rebase` by setting
`stash.useBuiltin=true` and `rebase.useBuiltin=true`, respectively,
(the latter already worked for the top-level `git rebase` command and
the `--am` backend, and now it also works for the interactive backend).

This merges the builtin stash.
Upstream Git did not integrate it into any stable integration branch
yet, but the performance improvements are substantial enough,
especially on Windows, that we really, really, really want to have it
early.

We recently converted both the `git rebase` and the `git rebase -i`
command from Unix shell scripts to builtins.
The former has a safety valve allowing to fall back to the scripted
`rebase`, just in case that there is a bug in the builtin `rebase`:
setting the config variable `rebase.useBuiltin` to `false` will
fall back to using the scripted version.
The latter did not have such a safety hatch.
Let's reinstate the scripted interactive rebase backend so that `rebase.useBuiltin=false` will not use the builtin interactive rebase,
just in case that an end user runs into a bug with the builtin version
and needs to get out of the fix really quickly.
This is necessary because Git for Windows wants to ship the builtin
rebase/interactive rebase earlier than core Git: Git for Windows
v2.19.0 will come with the option of a drastically faster (if a lot
less battle-tested) `git rebase`/`git rebase -i`.
As the file name `git-rebase--interactive` is already in use, let's
rename the scripted backend to `git-legacy-rebase--interactive`.
A couple of additional touch-ups are needed (such as teaching the
builtin `rebase--interactive`, which assumed the role of the
`rebase--helper`, to perform the two tricks to skip the unnecessary
picks and to generate a new todo list) to make things work again.

This simply copies the version as of v2.19.0-rc0 verbatim. As of now,
it is not hooked up (because it needs a couple more changes to work);
The next commit will use the scripted interactive rebase backend from
`git rebase` again when `rebase.useBuiltin=false`.

strbuf_vinsertf inserts a formatted string in the middle of an existing
strbuf value. It makes room in the strbuf by moving existing string to
the back, then formats the string to insert directly into the hole.
It uses vsnprintf to format the string. The buffer size provided in the
invocation is the number of characters available in the allocated space
behind the final string. This does not make any sense at all.
Fix it to pass the length of the inserted string plus one for the NUL.
(The functions saves and restores the character that the NUL occupies.)

After `git add -N <file>`, the index is in a special state. A state for
which the built-in stash was not prepared, as it failed to initialize
the `rev` structure in that case before using `&rev.pending`. If
`reset_tree()` returns a non-zero value, `stash_working_tree()`
calls `object_array_clear()` with `&rev.pending`. If `rev` is not
initialized, this causes a segmentation fault.
Prevent this by initializing `rev` before calling `reset_tree()`.
This fixes https://github.com/git-for-windows/git/issues/2006.

Add a GIT_TEST_STASH_USE_BUILTIN=false test mode which is equivalent
to running with stash.useBuiltin=false. This is needed to spot that
we're not introducing any regressions in the legacy stash version
while we're carrying both it and the new built-in version.
This imitates the equivalent treatment for the built-in rebase in
62c23938fa (tests: add a special setup where rebase.useBuiltin is off,
2018-11-14).

We recently converted the `git stash` command from Unix shell scripts
to builtins.
Let's end users a way out when they discover a bug in the
builtin command: `stash.useBuiltin`.
As the file name `git-stash` is already in use, let's rename the
scripted backend to `git-legacy-stash`.
To make the test suite pass with `stash.useBuiltin=false`, this commit
also backports rudimentary support for `-q` (but only *just* enough
to appease the test suite), and adds a super-ugly hack to force exit
code 129 for `git stash -h`.

The old shell script `git-stash.sh` was removed and replaced
entirely by `builtin/stash.c`. In order to do that, `create` and
`push` were adapted to work without `stash.sh`. For example, before
this commit, `git stash create` called `git stash--helper create
--message "$*"`. If it called `git stash--helper create "$@"`, then
some of these changes wouldn't have been necessary.
This commit also removes the word `helper` since now stash is
called directly and not by a shell script.

This commits introduces a optimization by avoiding calling the
same functions again. For example, `git stash push -u`
would call at some points the following functions:
* `check_changes()` (inside `do_push_stash()`)
* `do_create_stash()`, which calls: `check_changes()` and
`get_untracked_files()`
Note that `check_changes()` also calls `get_untracked_files()`.
So, `check_changes()` is called 2 times and `get_untracked_files()`
3 times.
The old function `check_changes()` now consists of two functions:
`get_untracked_files()` and `check_changes_tracked_files()`.
These are the call chains for `push` and `create`:
* `push_stash()` -> `do_push_stash()` -> `do_create_stash()`
* `create_stash()` -> `do_create_stash()`
To prevent calling the same functions over and over again,
`check_changes()` inside `do_create_stash()` is now placed
in the caller functions (`create_stash()` and `do_push_stash()`).
This way `check_changes()` and `get_untracked files()` are called
only one time.

There is a change in behaviour with this commit. When there was
no initial commit, the shell version of stash would still display
a message. This commit makes `push` to not display any message if
`--quiet` or `-q` is specified. Add tests for `--quiet`.
