diff: unify calls to diffline

diffline was called from trydiff for binary diffs and from unidiff
for text diffs. In this patch we unify those calls into one.

diffline is also a header, not part of diff mechanisms, so it makes
sense to remove that responsibility from the mdiff module. In
upcoming patches we will move diffline to patch module and
keep grouping responsibilities.
