gitweb: New improved formatting of chunk header in diff

Browse Source 
If we have provided enough info, and diff is not combined diff,
and if provided diff line is chunk header, then:
* split chunk header into .chunk_info and .section span elements,
  first containing proper chunk header, second section heading
  (aka. which function), for separate styling: the proper chunk
  header is on non-white background, section heading part uses
  slightly lighter color.
* hyperlink from-file-range to starting line of from-file, if file
  was not created.
* hyperlink to-file-range to starting line of to-file, if file
  was not deleted.
Links are of invisible variety (and "list" class).
