f807905786 opus: properly create channel mapping tables 
There are two of them, unintuitively enough; the one passed
to the encoder should not be the one that gets written to the
file. The former maps the input to an ordering which puts
paired channels first, while the latter moves the channels
to Vorbis order. So add code to calculate both, and we now
have properly paired channels where appropriate.

8ac75d10fd 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.

605d407b16 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.

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.

ccc04a1529 opusenc: do not include variable fields in caps

to be in the caps.

310daa5096 opusdec: allow negotiation of rate/channels with downstream

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.
