Round trip wav->mp3->wav now preserves the correct number of samples.
Remuxing mp3->mp3 with -c:a copy also preserves any existing gapless
metadata in the Info tag.
The code in libmp3lame.c to set AV_PKT_DATA_SKIP_SAMPLES was mostly
copied from libopusenc.c.
Jon Toohill (2):
lavc/libmp3lame: send encoder delay/padding in packet side data
lavf/mp3enc: write encoder delay/padding upon closing
