cf655d1643 Revert "apngdec: use side data to pass extradata to the decoder" 
This reverts commit e0c6b32046.

Said commit changed the behavior of the demuxer and decoder in a non
backwards compatible way.
Demuxers should make extradata available at init if possible, and send
new extradata as side data within a packet if needed.

A better fix for the remuxing crash will follow.
