In ffmpeg, the implementation of webm is a subset of matroska. In

The decoder currently only uses 72 bytes of 1376; furthermore,
the GetBitContext in OpusRangeCoder is unused by the encoder,

Since commit 4fc2531fff112836026aad2bdaf128c9d15a72e3 opus.c
contains only the celt stuff shared between decoder and encoder.
meanwhile, opus_celt.c is decoder-only. So the new names
reflect the actual content better than the current ones.

This fixes an issue where a timestamp attribute may have a valid zero
value (the UNIX epoch 1970-01-01T00:00:00), but is misinterpreted by
dashdec as being unassigned. This changes the logic that calculates
segment numbers and makes the stream undecodable by dashdec.
