This commit will properly set the duration field of Opus AVPackets.
Currently, duration is set to 0 on Opus packets from the RTP demuxer.
The Ogg muxer depends on the duration field to properly compute the page granule
value. Without a proper duration, the granule will be wrong, and result in
negative pts values in ogg files.
See oggenc.c:657 (ogg_write_packet_internal)
This commit calculates using the opus_duration function, which was copied
from oggparseopus.c
I moved this functionality and the existing opus extradata functionality
(added by me in 6c24f2b) into a new rtpdec_opus.c file.
