Also changes some default values for options after this change.
This makes distinction between feedback and wet option.
Before they would produce same output if values were swapped.
Currently a repeating setup request (with the same stream id) will
simply overwrite rtp_handle/transport_priv without freeing the
resources first. This is fixed by closing the previous setup request.

They add considerable complexity to frame-threading implementation,
which includes an unavoidably leaking error path, while the advantages
of this option to the users are highly dubious.
It should be always possible and desirable for the callers to make their
get_buffer2() implementation thread-safe, so deprecate this option.

The FLAC muxer currently stores an attached picture corresponding to an
AVStream in AVStream.priv_data. The AVPacket contained therein is
unreferenced after it has been written. The AVPacket structure itself is
then freed generically as AVStream.priv_data.
And this can lead to memleaks if an attached picture is not written:
It might be because the trailer is never written or because writing
a previous attached picture failed in case error_recognition is set
to explode.
Therefore free the packets properly (i.e. with av_packet_free())
in the muxer's deinit function.

These two extensions and two features are both optionally used by
libplacebo to speed up rendering, so it makes sense for libavutil to
automatically enable them as well.
Vulkan formats with a PACK suffix define native endianess.
Vulkan formats without a PACK suffix are in bytestream order.
Pixel formats with a LE/BE suffix define endianess.
Pixel formats without LE/BE suffix are in bytestream order.
This relies on the fact that host memory is always going to be required
to be aligned to the platform's page size, which means we can adjust
the pointers when we map them to buffers and therefore skip an entire
copy. This has already had extensive testing in libplacebo without
problems, so its safe to use here as well.
Speeds up downloads and uploads on platforms which do not pool their
memory hugely, but less so on platforms that do.
We can pool the buffers ourselves, but that can come as a later patch
if necessary.
