Update mxf_set_audio_pts to use the container-provided information.

The UL is marked as "to be changed in the future", but the current
samples in the wild do use it.

And use it to print non-parsed ULs.

Leftover from fbc0b865.

The file does not require atomic.h. Also kills function redefinition warnings.

This avoids annoying warnings about unused functions. The compatibility
wrapper is designed to provide a complete (stub) API, so some functions
being unused by some files is natural and no reason for a warning.

Also fixes an unused variable warning with zlib disabled.

ff_MPV_common_init requires the frame dimensions which get parsed in
h261_decode_picture_header.

ff_MPV_common_init requires the frame dimensions which get parsed in
*_decode_picture_header.

One step in untangling the mpegvideo code and fixing some problems in
the order that initialization is being done in h263dec and h261dec.

Also fix some comment typos.

It is basically a wrapper around av_get_audio_frame_duration(), with a
fallback to AVCodecContext.frame_size. However, that field is set only
when the stream codec context is actually used for encoding or decoding,
which is discouraged.

For muxing, it is generally the responsibility of the caller to set the
packet duration.
For demuxing, if the duration is not stored at the container level, it
should be set by the parser.

Therefore, removing the frame_size fallback should not break any
important case.

It more accurately describes what this function does

The cur_*auth_type variables were set before the http_connect call
prior to 6a463e7f - their sole purpose is to record the
authentication type used to do the latest request, since parsing
the http response sets the new type in the auth state.

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.

Currently, only onMetaData is used, but some providers (wrongly)
put metadata into onCuePoint events, and it's still nice to be
able to use that data.

onCuePoint events also present metadata slightly differently than
onMetaData events: all metadata is found inside an object called
"parameters". In order to extract this metadata, it's easiest to
recurse through the object tree and pull out anything found in
child objects and put it in the top-level metadata.

The only flags, for now, indicate if metadata was updated and are set after each call to
av_read_frame(). This comes with the caveat that, on stream start, it might not be set properly
as packets might be buffered in AVFormatContext.packet_buffer before being given to the user
in av_read_frame().
