msdk: vpp: Add supprot for dmabuf-import
...
MediaSDK requires all the input and output buffers to be
pre-allocated during init phase and this won't work with
current design of GStreamer or gst-msdk. But this can be
done with https://bugzilla.gnome.org/show_bug.cgi?id=795747
There is a workaround possible as per
https://github.com/Intel-Media-SDK/MediaSDK/issues/155#issuecomment-381790504
by faking the mem-id during MFXInit.
This patch do this in gst-msdk by replacing the MemID of mfxSurface
with dmabuf-backed vasurface dynamically.
Important: v4l2 ! msdkvpp won't work without a copy because
of the GMMLib (https://github.com/intel/gmmlib ) memory restrictions.

msdkvpp: Disable passthrough if memory capsfeature changes
...
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.

msdk: vpp: Add dmabuf-export support
...
Currenly, the dmabuf buffer pool can be negotiated
only through DMABuf capsfeatures.
This will not allow to negotiate dmabuf support with
v4l2src (v4l2src ! msdkvpp) where v4l2src always export
the dmabuf based memory with out using the DMABuf capsfeatures.
So it requires fix based on:

msdk: vpp: Allocation query fixes
...
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.
