The only parameters needed by the demuxers are the sample rate and sample
count, which can be trivially extracted manually, without resorting to
an avpriv function.

Originally, AVFormatContext and a metadata dict were provided to ff_vorbis_comment(),
but this presented issues if an AVStream was being updated or the metadata on
AVFormatContext wasn't actually being updated. To remedy this, ff_vorbis_stream_comment()
explicitly updates a stream's metadata and sets any necessary flags.

ff_vorbis_comment() does not modify any flags, and any calls to it that update
AVFormatContext's metadata (just a single call) must also update
AVFormatContext.event_flags after detecting any metadata changes to the provided
dictionary, as signaled by a positive return value.

It is commonly stored in a vorbiscomment block in codec private data.

Not having the header for a codec is a tell-tale of a broken file.

We need to parse the individual packet durations when there is more than one
packet in a page.

It's supposed to be called only from (de)muxers.

Specifically, ff_flac_parse_streaminfo, ff_flac_is_extradata_valid and
ff_flac_parse_block_header
