670c365400 opus: switch to multistream API
It's very similar to the basic API, and is a superset ot it,
which will allow encoding and decoding more than 2 channels.

5c8812f58c opusdec: implement replay gain
It would ideally be better to leave this to a rgvolume element,
but we don't control the pipeline. So do it by default, and allow
disabling it via a property, so the correct volume should always
be output.

bfdda8e09a opusdec: add in-band FEC support
This allows reconstruction of lost packets if FEC info is included
in the next packet, at the cost of extra latency. Since we do not
know if the stream has FEC (and this can change at runtime), we
always incur the latency, even if we never lose any frame, or see
any FEC information. Off by default.

b226e8a085 opusenc: allow setting most properties at PLAYING time
Opus allows these to be changed during encoding, transparently
to the decoder.

ee723996db opusenc: bound the bitrate to more sensible values
Go from the bounds mentioned in the spec, and allow some more
variation.
In particular, don't allow silly low bitrates, and allow reaching
the maximum useful bitrate.

bb39c86fdf opusenc: fix crash on pathological parameters
Asking for 1 bit/s would select a 0 byte buffer, leading
to a crash. Buffer size is now controlled by a max-payload-size
property, which can't be less than 2.

95ae14f8b4 opusenc: do not push header buffers
Opus headers appear only when muxed in Ogg, so only place them
on the caps, where oggmux will find them, but other elements will
be blithely unaware of them.

7030b04f5e opus: make opusparse set headers on caps
Header-on-caps code moved to a new shared location to avoid
duplicating the code.

ccc04a1529 opusenc: do not include variable fields in caps
Those can vary from one packet to the next, so have no reason
to be in the caps.

framing used by the Opus test vectors.

310daa5096 opusdec: allow negotiation of rate/channels with downstream
Since an opus stream may be decoded to any (sensible) rate,
and either stereo or mono, we try to accomodate downstream.

ffc4408d53 opusdec: rewrite logic
Parameters such as frame size, etc, are variable. Pretty much
everything can change within a stream, so be prepared about it,
and do not cache parameters in the decoder.
