So far msdk produced dmabuf fds are non-mappable.
If user wants to download the content of underlined surfaces,
dmabufcapsfeature negotiated pipeline will fail. So if the input surface
is dmabuf and downstream doesn't have support for dmabuf capsfeatures,
we do the vpp (no passthrough) and produce the mappable videomemory
buffers.

prpose_allocation:
-- always instantiate a pool for for upstream
-- use async_depth + 1 as min buffer count
decide_allocation:
-- always create a new bufferpool for source pad.
Each of the msdk element has to create it's own mfxsurfacepool
which is an msdk contraint. For eg: Each Msdk component (vpp, dec and
enc)
will invoke the external Frame allocator for video-memory usage
So sharing the pool between gst-msdk elements might not be a good idea.

If the "output-cc" property is set to TRUE and there is CC present
in the VBI Ancillary Data, they will be extracted and set on the
outgoing buffer as GstVideoCaptionMeta.
Only CDP packets are supported.

This adds entry for new DRM driver from xilinx
called "xlnx" which supports atomic modesetting.
We have kept entry for older DRM driver "xilinx_drm"
for backward compatility with a note describing
deprecation.

The clock seems to have a lot of drift (or we're using it incorrectly)
which causes buffers to be late on the sink and get dropped.
Disable till someone can investigate whether our usage of the API is
incorrect (it looked correct to me) or if something is wrong.
Since cuda-tools 9.0, nvcuvid.h is replaced by dynlink_nvcuvid.h.
This patch changes nvdec to use run-time dynamic linking if
cuda-tools version >= 9.
nvenc does not require any change since its necessary headers are
still available.

Using the default value (InterleavedDec == MFX_SCANTYPE_UNKNOWN)
causing issues with non-interleaved sample decode. Ideally the usage
of MFXVideoDECODE_DecodeHeader should fix these type of issue, but
it seems to be not. But hardcoding the InterleaveDec to
MFX_SCANTYPE_NONINTERLEAVED
is fixing the problem and fortunately msdk seems to be taking care of
Interleaved samples
too .So let's hardcode it for now.

We can just return the template caps till the device is opened when
going from READY -> PAUSED. This fixes a CRITICAL when calling
ELEMENT_ERROR before the ringbuffer is allocated.
Also fixes a couple of leaks in error conditions.

Now, when you set loopback=true on wasapisrc, the `device` property
should refer to a sink (render) device for loopback recording.
If the `device` property is not set, the default sink device is used.
This patch includes:
1\ Implements MsdkDmaBufAllocator and allocation of msdk dmabuf memroy.
2\ Each msdk dmabuf memory include its own msdk surface kept by GQuark.
3\ Adds new option GST_BUFFER_POOL_OPTION_MSDK_USE_DMABUF
