3062f1b6b0 msdkdec: Apply the modified memory allocation logic
We did several things to enable the new memory logic in msdkdec:
(1) We always use video memory for decoder in linux path;
(2) We give negotiated pool to alloc_pool stored in GstMsdkContext which
will be used in callback mfxFrameAllocator:Alloc to alloc surfaces as
MediaSDK needs, and this pool is also available for decoder itself;
(3) We modify decide_allocation process, that is we make pool negotiaion
before gst_msdk_init_decoder to ensure the pool is decided and ready for
use in mfxFrameAllocator:Alloc callback; then we will consider the case
when we need to do the gpu to cpu copy.
(4) In gst_msdkdec_finish_task, we modify the way for copy following the
logic in (3).

8459349963 msdkallocator_libva: Rewrite gst_msdk_frame_alloc
Rewrite gst_msdk_frame_alloc and name it as xxx_2 before applying it.
It uses negotiated bufferpool stored in GstMsdkContext to allocate buffers
in the callback MfxFrameAllocator:Alloc, then extract VASurface from buffer,
wrap it as mfxMemIDs and pass these IDs to MediaSDK/oneVPL.

86d22b2e38 msdkallocator: add a parameter to function gst_msdk_import_to_msdk_surface
Add a flags parameter to function gst_msdk_import_to_msdk_surface and
move the function declaration to gstmsdkallcator.h to prepare for adding
Windows implementation.

4c6b719445 msdkvpp: Import buffer to msdk_surface
If the buffer is not msdk_buffer, we can try to directly import the
attached memory (i.e. va mem and dmabuf mem) by applying the common
uitl function: import_to_msdk_function ().

Here add a flag "from_qdata" in GstMsdkSurface to handle the cropping case,
we should avoid updating the crop values when msdk_surface is from the
memory's qdata, because the crop info from this surface is the already
updated one.

2854af85fd msdk: Add help functions to get mfxFrameSurface1 from GstBuffer and wrap it as GstMsdkSurface
Note that the memory abstraction for system memory is for windows path.
