By putting the call in a subshell, the problem of it spilling
cleanup-decision from a previous library to other libraries is avoided.
For example, it could have already cleaned up cuda_extralibs in a
previous library that depended on cuda. Then when it gets to avutil, it
will never pick up the dependency of avutil to cuda, which depends on
libdl, which in turn results in a missing -ldl extralib, resulting in
link failures in certain configurations.

This avoids having to use either "dumpbin -headers" to find out
the current architecture, or pass $ARCH from configure to deduce it.
When configuring with --disable-asm, ARCH is equal to "c", which doesn't
give any indication of what symbol prefix is to be used.

- Minor SHFLAGS simplification
- Coalesce some threads tests
alloc_frame_buffer in ff_alloc_picture asserts that the linesize
of planes 1 and 2 are the same. If the pixfmt has a single uv
plane, like NV12, this won't be true.
So, let's only do this check if there are more than 2 planes.
We never hit this with previous hw formats because they don't set
linesize to meaningful values, but the cuda hw format sets the
values based on the underlying data layout.
After c2a8f0fcbe this can happen on normal edit lists starting on a B-frame.

The macros for ICC and MSVC correctly push and pop the diagnostic
state of the compiler when disabling deprecation warnings. The
ones for clang/gcc should do the same. Without this, if a blanket
deprecation warning is applied to the code base it'll be flipped
back on incorrectly with FF_ENABLE_DEPRECATION_WARNINGS.

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.

This is a partial fix - to fix videotoolbox fully (with multithreaded
hwaccel decoding), much more work would be required.
Before this change, an assertion failure would trigger:
$ ffmpeg -hwaccel videotoolbox -hwaccel_output_format videotoolbox_vld -i h264.ts -f null -y /dev/null
Assertion (frame->private_ref && frame->private_ref->size == sizeof(FrameDecodeData)) || !(avctx->codec->capabilities & (1 << 1)) failed at libavcodec/decode.c:620

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.
