stash: optionally use the scripted version again
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`.
