Works only with video stream.
First pass without seeking -- counts crcs of a frames and store it in an array.
After that it seeks a lot in different places and checks if crcs of these frames and crcs of frames in array are the same.

If the return value doesn't fit in a single register rdx/edx can in some
cases be used in addition to rax/eax.

Doesn't affect any of the existing checkasm tests but might be useful later.

Also comment the relevant code a bit better.

Now we no longer have to rely on function pointers intentionally
declared without specified argument types.

This makes it easier to support functions with floating point parameters
or return values as well as functions returning 64-bit values on 32-bit
architectures. It also avoids having to explicitly cast strides to
ptrdiff_t for example.

This fixes fate when FF_API_ERROR_RATE=0.

Invalid buffer ids are defined by VA_INVALID_ID. Use that through out
vaapi_*.c support files now that we have private data initialized and
managed by libavcodec. Previously, the only requirement for the public
vaapi_context struct was to be zero-initialized.

This fixes support for 3rdparty VA drivers that strictly conform to
the API whereby an invalid buffer id is VA_INVALID_ID and the first
valid buffer id can actually be zero.

Move libavcodec managed objects from the public struct vaapi_context
to a new privately owned FFVAContext. This is done so that to clean up
and streamline the public structure, but also to prepare for new codec
support, thus requiring new internal data to be added in there.

The AVCodecContext.hwaccel_context, that holds the public vaapi_context,
shall no longer be accessed from within vaapi_*.c codec support files.

Deprecate older VA pixel formats (MOCO, IDCT) as it is now very unlikely
to ever be useful in the future. Only keep plain AV_PIX_FMT_VAAPI format
that is aliased to the older VLD variant.

This is an API change.
