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.

Muxers can check AVCodecParameters.initial_padding for the
encoder+decoder delay, and read the AV_PKT_DATA_SKIP_SAMPLES
side data from the last packet for the encoder padding.
This change also fixes the first_discard_sample calculation
which erroneously included the decoder delay. Decoder delay

This preserves changes to fields of AVCodecParameters that
get updated during encoding, such as trailing_padding
(which may not be known until encoding is complete).
