In 45c1389c31 (stash: convert apply to builtin, 2018-12-20), we
introduced code that is the equivalent of `git write-tree && git
read-tree`. But the original shell script only called `git write-tree`
(because the read-tree would obviously be a no-op). So let's skip the
reset_tree() call that is the equivalent that that `git read-tree`.

In 9a67cb4f1f (stash: convert push to builtin, 2018-12-20), we started
to call `git apply -R --index` and `git reset --hard`, but held onto the
now-stale index in memory. Let's discard it.

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`.

This simply copies the version as of sd/stash-wo-user-name verbatim. As

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

Add the drop and clear commands to the builtin helper. These two
are each simple, but are being added together as they are quite
related.
We have to unfortunately keep the drop and clear functions in the
shell script as functions are called with parameters internally
that are not valid when the commands are called externally. Once
pop is converted they can both be removed.

Add a builtin helper for performing stash commands. Converting
all at once proved hard to review, so starting with just apply
lets conversion get started without the other commands being
finished.
The helper is being implemented as a drop in replacement for
stash so that when it is complete it can simply be renamed and
the shell script deleted.
Delete the contents of the apply_stash shell function and replace
it with a call to stash--helper apply until pop is also
converted.

In 3bc2111fc2 (stash: tolerate missing user identity, 2018-11-18),
`git stash` learned to provide a fallback identity for the case that no
proper name/email was given (and `git stash` does not really care about
a correct identity anyway, but it does want to create a commit object).
In preparation for the same functionality in the upcoming built-in
version of `git stash`, let's offer the same functionality as an API
function.

request #2088 from dscho/test-oid-fix-windows, 2019-02-24), we can
safely pull in the commit history of origin/master in a fake merge (i.e.
