[PATCH 4/8] gitweb: Push formatting diff lines to print_diff_chunk()

[Michał Kiedrowicz <michal.kiedrowicz@xxxxxxxxxxxxx>]

Now git_patchset_body() only calls diff_line_class() (removed from
process_diff_line()). The latter function is renamed to
format_diff_line() and is called from print_diff_chunk().

This is a pure code movement, needed for processing raw diff lines in
the accumulator in print_diff_chunk(). No behavior change is intended by
this change.
