[PATCH v6 3/6] stash: refactor stash_create

[Thomas Gummerer]

Refactor the internal stash_create function to use a -m flag for
specifying the message and -u flag to indicate whether untracked files
should be added to the stash.

This makes it easier to pass a pathspec argument to stash_create in the
next patch.

The user interface for git stash create stays the same.
