Pass an HTTP message type to all HTTP subdissectors.

This gets complicated, because those subdissectors might be called by
other dissectors as well.  We need a better way of passing that sort of
out-of-bound information.

Pull some routines used for processing Content-Type parameters into
common code; we can't guarantee that the media parameters passed in
would be writable (passing it as *the* data hid that; passing a
structure with that *and* the HTTP message type revealed it), so don't
convert it to lower-case in place.

Use that information, if available, to determine whether an IPP message
is a requet or a response.
