9121131f31 opusdec: fix 120 ms buffers being wrongly emitted
Using the max 120 ms buffer size to ensure we have enough space
for decoded data meant that Opus could actually return 120 ms'
worth of data.

b0866b9cc1 opusdec: interpret zero duration as unknown
This fixes missing audio when we get buffers with zero
duration, denoting unknown duration. When several such
buffers are received in a row, they're all at the same
timestamp, with zero duration.

a6ced9cbc8 opusdec: fix "buffer too small" error
Always supply a buffer with max size to the decoder, as we
can't really decide how many samples will be in the lost packet
based on the timestamps we get.

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.

1ef601e7d3 opus: fix FEC
FEC may only be used when PLC is enabled on the audio decoder,
as it relies on empty buffers to generate audio from the next
buffer. Hooking to the gap events doesn't work as the audio
decoder does not like more buffers output than it sends.

The length of data to generate using FEC from the next packet
is determined by rounding the gap duration to nearest. This
ensures that duration imprecision does not cause quantization
to 2.5 milliseconds less than available. Doing so causes the
Opus API to fail decoding. Such duration imprecision is common
in live cases.

The buffer to consider when determining the length of audio
to be decoded is the previous buffer when using FEC, and the
new buffer otherwise. In the FEC case, this means we determine
the amount of audio from the previous buffer, whether it was
missing or not (and get the data either from this buffer, or
the current one if the previous one was missing).

started the decoder in the middle of the stream.

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.

This way we let opusdec do the resampling if needed and don't carry

While Opus always uses 48kHz internally, this information from the
header specifies which frequencies are safe to drop.
