parentstash: simplify option parser for create (diff)

stash: introduce 'git stash store'
save_stash() contains the logic for doing two potentially independent operations; the first is preparing the stash merge commit, and the second is updating the stash ref/ reflog accordingly. While the first operation is abstracted out into a create_stash() for callers to access via 'git stash create', the second one is not. Fix this by factoring out the logic for storing the stash into a store_stash() that callers can access via 'git stash store'. Like create, store is not intended for end user interactive use, but for callers in other scripts. We can simplify the logic in the rebase.autostash feature using this new subcommand.
