range-diff: use parse_options() instead of diff_opt_parse()

Diff's internal option parsing is now done with 'struct option', which makes it possible to combine all diff options to range-diff and parse everything all at once. Parsing code becomes simpler, and we get a looong 'git range-diff -h' Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
