This code was modelled after the Vorbis and Theora decoders, as
Kate uses the same kind of packetizing. A difference is that the number
of headers isn't fixed but specified in the first header, so i_num_headers
is initialized to 0 first, before the actual number is known. I suppose a
different way of doing it would be to initialize it to 255 (number of headers
is encoded as 8 bits), but rereading this, it does look correct to me: it
just doesn't assume all headers have been seen if none have been seen
(as the BOS header will always be there).

Thanks
