HTTP: improve sub-classification (#1696)
Content-matched sub-protocols (DASH, IPP, MPEGDASH...) shouldn't ovewrite the previous master protocol (if any; usually HTTP). Furthermore. the HTTP dissector shouldn't update the classification (in the extra-dissection code path) if a content-matched sub-protocols has already been found. This commit should address the first part of the changes described in #1687.
