6bc6b6ebbf opusdec: handle missing buffers with no duration
If buffer duration is missing, it is parsed from the packet data.
This is not foolproof, since Opus can change durations on the
fly.

e5409361b8 opusdec: Fix PLC frame size calculations
Previously, PLC frames always had a length of 120ms, which caused audio
quality degradation and synchronization errors. Fix this by calculating an
appropriate length for the PLC frame.

The length must be a multiple of 2.5ms. Calculate a multiple of 2.5ms that
is nearest to the current PLC length. Any leftover PLC length that didn't
make it into this frame is accumulated for the next PLC frame.

ad4da8dd0e opus: set author to myself, and update copyright notices
because as slomo noted, in fact pretty much all the code in there is mine.

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.

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.

Copy the celt plugin and convert it to Opus.  Mostly works.
