[PATCH/RFC] Restructure some of the checkout opts.

[Jared Hance <jaredhance@gmail.com>]

Previously, most opts in `builtin.checkout.c' had been an instance of
`struct checkout_opts'. It appears that some of the opts that were
perhaps added later were not in the struct. Move them into the struct
in order to maintain consistency.
