[PATCH 06/10] revert: Separate cmdline parsing from functional code

[Ramkumar Ramachandra <artagnon@gmail.com>]

Make cmd_cherry_pick and cmd_revert call parse_args and parse all the
command-line arguments into an opts structure before sending it off to
a simplified pick_commits function.  pick_commits, in turn will set up
the revision walker and call do_pick_commit in a loop- later in the
series, it will serve as the starting point for continuation.
