Also simplify it and make it always log the error.
This fixes for example the image2 muxer when used with an URL which also
contains the protocol:
ffmpeg -f lavfi -i testsrc -vframes 10 -atomic_writing 1 file:out%d.png

This is done so that its data is really owned by the packet.
This was already true for the current callers.

The documentation of ff_packet_list_get currently didn't match the
actual usage:
1. It said that the destination packet is supposed to be initialized.
But this makes no sense given that it will be overwritten completely and
flacenc, mp3enc and ttaenc ignored this.
2. ff_packet_list_get returns an int, although it can't fail in case the
packet list is not empty (for which there is an assert). Again, several
callers didn't check for any return value.
In both cases, the documentation has been adapted to match actual usage.

This will replace the 1024 character limited filename field. Compatiblity for
output contexts are provided by copying filename field to URL if URL is unset
and by providing an internal function for muxers to set both url and filename
at once.

It's completely absurd that libavcodec would care about libavformat
locking, but it was there because the lock manager was in libavcodec.
This is more stright forward. Changes ABI, but we don't require ABI
compatibility currently.
Every bitstream filter behaves as intended now, so there's no need to
wait for the first packet of every stream.

This merges commits 8e2ea69135 and
096a8effa3 by Anton Khirnov, with the
following change:
- extract_extradata_check() is added to know if the codec is supported
by the bsf before trying to initialize it. This behaviour is similar to
the old AVCodecParser.split checks.
The FATE reference changes are due to the filtered out NAL units that
the old AVCodecParser.split implementation left alone.
Decoding is unchanged as the functions that parse extradata simply
ignored said unnecessary NAL units.

This reverts commit 1c193ac1f9, reversing
changes made to 7ebc9f8df4.
Several FATE tests started failing after this merge, so it's reverted
until it can be properly fixed.
This allows a consumer to run the muxer's init function without actually
writing the header, which is useful in chained muxers that support
automatic bitstream filtering.

This also fixes a minor bug introduced in the codecpar conversion, where
the termination condition for extracting the extradata does not match
the actual extradata setting code. As a result, the packet durations
made up by lavf go back to their values before the codecpar conversion.
That is of little consequence since that code should eventually be
dropped completely.

As long as caller only writes packets using av_interleaved_write_frame
with no manual flushing, this should allow us to always have accurate
durations at the end of fragments, since there should be at least
one queued packet in each stream (except for the stream where the
current packet is being written, but if the muxer itself does the
cutting of fragments, it also has info about the next packet for that
stream).

This can be used for formats which write all format metadata as string to
files, therefore non-standard creation times such as 'now' will be parsed.
The standardized creation time is UTC ISO 8601 with microsecond precision.
