avcodec: fix whitespace on AVPanScan struct definition

avformat/http: fix chunked response w/ multiple_requests=1

Currently if you use the multiple_requests=1 option and try to
receive a chunked-encoded response, http_buf_read() will hang forever.

After this patch, EOF is emulated once a 0-byte final chunk is
received by setting a new flag. This flag is reset in ff_http_do_new_request(),
which is used to make additional requests on the open socket.

avcodec/videotoolbox: create avcC even when h264 extradata is missing

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

avcodec/videotoolbox: use decode_params to propagate H264 PPS changes and restart on SPS changes

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.

fed into the decoder session, and for the session to be recreated when

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
