stash: optionally use the scripted version again

2019-03-07T00:41:40Z

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`.

stash: add back the original, scripted `git stash`

2019-03-07T00:41:40Z

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

stash: convert `stash--helper.c` into `stash.c`

2019-03-07T00:41:40Z

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.

stash: convert show to builtin

2019-03-07T00:41:40Z

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`.
