format-patch: Add "--no-stat" as a synonym for "-p"

"-p" means "generate patch" in 'git log' and 'git diff', so it's quite surprising that it means "suppress diffstat" in 'git format-patch'.

Keep the "-p" option for backward compatibility, but add "--no-stat" as a more intuitive synonym. For backward compatibility with scripts, we must allow combinations of --stat and --no-stat.

This patch is new.

Unfortunately, we must allow --no-stat and --stat (or alternatively complicate the implementation to allow -p and --stat, but not --no-stat and --stat). If that seems too strange, perhaps we are better off without this patch.
