Merge branch 'ph/diffopts'

* ph/diffopts:
Reorder diff_opt_parse options more logically per topics.
Make the diff_options bitfields be an unsigned with explicit masks.
Use OPT_BIT in builtin-pack-refs
Use OPT_BIT in builtin-for-each-ref
Use OPT_SET_INT and OPT_BIT in builtin-branch
parse-options new features.
