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.

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.

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.

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.

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.

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.
