Unfortunately I was forced to make the default -1 so you want to check
that the value is greater than 0 rather than just true.

Furthermore I think you will still want to add to Changelog making a
note that the matroska muxer will now listen to metadata_header_padding.
 That may also want a micro version bump so that library users can check.
