We recently converted the `git stash` command from Unix shell scripts
to builtins.
Just like we have `rebase.useBuiltin` to fall back to the scripted
rebase, to give end users a way out when they discover a bug in the
builtin command, this commit adds support for `stash.useBuiltin`.
This is necessary because Git for Windows wants to ship the builtin
stash 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 stash`.
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 v2.19.0-rc0 verbatim. As of now,
it is not hooked up.
The next commit will change the builtin `stash` to hand off to the
scripted `git stash` when `stash.useBuiltin=false`.

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.

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.

Add stash save to the helper and delete functions which are no
longer needed (`show_help()`, `save_stash()`, `push_stash()`,
`create_stash()`, `clear_stash()`, `untracked_files()` and
`no_changes()`).

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`.

Add stash show to the helper and delete the show_stash, have_stash,
assert_stash_like, is_stash_like and parse_flags_and_rev functions
from the shell script now that they are no longer needed.
In shell version, although `git stash show` accepts `--index` and
`--quiet` options, it ignores them. In C, both options are passed
further to `git diff`.

Add stash branch to the helper and delete the apply_to_branch

Checkout does not currently provide a function for checking out

first that we require here.

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.

Compared to `get_oid()`, `get_oidf()` has as parameters
a pointer to `object_id`, a printf format string and
additional arguments. This will help simplify the code
in subsequent commits.

We do not actually need -mconsole; it is the default. But it hurts to
have it, as it breaks the assumption of the mingw-w64-git package that
it can reuse the flags to link git-bash.exe. So let's remove it.
