f40ccb3811 opusenc: add upstream negotiation for multistream ability 
This will help elements that cannot deal with multistream,
such as the RTP payloader.

The caps now do not include a "streams" field anymore, but
a "multistream" boolean, since we have no real use for knowing
the exact amount of streams.

b48b3c2c86 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.

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.

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.

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.

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.
