631f42eee8 opusenc: only use mono streams for > 2 channels
I'm getting odd results with packing streams into stereo
streams, and using only mono streams is enough in all cases.

2e0e118676 opusparse: remove dead assigments
We now only keep a ref to the headers for later reuse.

f78c83a0b6 opusenc: do not cause the decoder to apply the channel mapping again
Since we already reorder channels, we do not want to write that
reordering in the header, or the decoder will do it again.

5da03cd2a4 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.

4bd5ef9bc5 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.

b80f52a729 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.

5e1df00674 opusenc: allow setting most properties at PLAYING time
Opus allows these to be changed during encoding, transparently
to the decoder.

5367aa8dbf 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.

49e08a1835 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.

da5c41930c opusparse: do not send headers through data path
Additionally, since Opus packets may change between stereo
and mono as the encoder sees fit, assume two channels when
we do not see a header, and use the header value otherwise.

c0695ba7f2 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.

15b5fecf30 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.

a02e18917f 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.

d10cbd0268 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.
