[PATCH v3 05/14] checkout: move 'confict_style' and 'dwim_..' to checkout_opts

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

These local variables are referenced by struct option[]. This struct
will soon be broken down, moved away and we can't rely on local
variables anymore. Move these two to struct checkout_opts in
preparation for that.
