Also remove now unused AVFormatParameters struct and
AVOutputFormat.set_parameters().

If no data was seen for a stream decoder are returning 0 when fed with
empty packets for flushing. We can stop flushing when the decoder does
not return delayed delayed frames anymore. Changes try_decode_frame()
return value to got_picture or negative error.

The H.264 decoder needs SPS and PPS for initialization during
multi-threaded decoding. When probed single-threaded SPS and PPS are
copied to extradata and are available for proper initialization of
the decoder before the first frame is decoded.

This fixes various problems with getting stream info. For example playback of the
file of Ticket88. Multithreaded find_stream_info should be reenabled
once it works correctly

The decoders should not only be flushed on EOF or error, but also when
e.g. probe size was reached.
It is best to just always flush by default and only disable it
explicitly when we know that we have everything we need.

This means that avformat_find_stream_info() now works properly with
multiple threads, so there's no need to force thread count to 1.

This works around issues arising from inputs that claim to have a
filesize of 0.

Fix the iformat/oformat typo.

It sets the supplied AVFormatContext pointer to NULL after freeing it,
which is safer and its name is consistent with other lavf functions.

Also deprecate av_close_input_file().

And remove all its uses.

The information is relevant, but under normal circumstances
it raises far too many false alarms.
