  *) mod_http2: connection terminology renamed to master/secondary.
     trunk patch: http://svn.apache.org/r1878926
                  http://svn.apache.org/r1879156
     2.4.x patch: https://svn.apache.org/repos/asf/httpd/httpd/patches/2.4.x/h2-master-secondary.patch
     +1: icing, ylavic, minfrin
     ylavic: nitpicking, mixed "H2_secondary_IN" and "H2_secondary_OUT" case to
             register the filters, but not for adding them. IIRC filters names
             are case insentive so shouldn't matter, just popped at my eyes..
     icing: updated patch and added r1879156 to fix the eye bleed.
     jailletc36: CHANGES could also be looked at if it makes sense to update the terminology
                 also here
