This includes the SEI_PREFIX/SEI_SUFFIX NALUs, which can contain
updates like HEVC_SEI_TYPE_ACTIVE_PARAMETER_SETS. Previously, hevc
samples with this SEI present would not playback correctly.

Removes the avctx->extradata_size requirement when creating avcC/hvcC, since
avctx->extradata is only used in the esds code path.

This fixes an issue where the VideoToolbox decoder would not work unless
avformat_find_stream_info() was called.

This fixes decoding of H264 video samples with SPS and PPS changes.

See for example https://s3.amazonaws.com/tmm1/videotoolbox/spschange.ts,
which previously stalled the decoder and failed to produce any new frames
after the SPS change.

Also see https://s3.amazonaws.com/tmm1/videotoolbox/ppschange.ts, which
uses multiple PPS and would previously cause VT decode failures.

If the VideoToolbox session needs to be restarted, and
videotoolbox_start() fails for some reason (for instance, if the video
is interlaced and the decoder is running on iOS), avcodec will return
AVERROR_EXTERNAL. This can be used by the API user to switch to another
decoder.

This callback will be used by the VideoToolbox H264 hwaccel so that it
can receive SPS and PPS NALUs. VideoToolbox requires PPS changes to be
fed into the decoder session, and for the session to be recreated when
the SPS changes.

The only reason videotoolbox wouldn't produce frames is if the data fed
to it was invalid, so returning AVERROR_INVALIDDATA makes sense here.

Further, it means AVERROR_EXTERNAL can be used in further commits to signal
fatal VideoToolbox errors, letting the user know that they need to fallback to
another decoder.

This allows decode_slice to be invoked multiple times before end_frame,
causing slices to accumulate before being fed into the VT decoder.

An upcoming commit will re-use decode_slice for parameter NALUs, so
they can be propagated into the VT decoder session along with slice
data.

These helpers will be used in later commits to automatically restart
the decoder session when SPS changes are encountered.

multiple_requests=1 is also set. Without an EOF to signal the end of
the last chunk, tls_read gets stuck forever trying to read more data
than is available. This occurs with the http protocol reproducibly,
because http.c always reads 4kb at a time, and the last chunk of an
http response is often much smaller.

After this commit, tls_read always returns any buffered plaintext
first before attempting to read more encrypted data off the
underlying tcp socket.

Variables used in inline assembly need to be marked with attribute((used)).
Static constants already were, via the define of DECLARE_ASM_CONST.
But DECLARE_ALIGNED does not add this attribute, and some of the variables
defined with it are const only used in inline assembly, and therefore
appeared dead. This change adds a macro DECLARE_ASM_ALIGNED that marks
variables as used.

This change makes FFMPEG work with Clang's ThinLTO.
