[PATCH 10/75] diff.h: avoid bit fields in struct diff_flags

Bitfield addresses cannot be passed around in a pointer. This makes it hard to use parse-options to set/unset them. Turn this struct to normal integers. This of course increases the size of this struct multiple times, but since we only have a handful of diff_options variables around, memory consumption is not at all a concern.
