375a50a876 msdk: add async depth from each msdk element to GstMsdkContext to be shared
In case that pipeline is like ".. ! decoder ! encoder ! ..." with using
video memory,
decoder needs to know the async depth of the following msdk element so
that it could
allocate the correct number of video memory.

Otherwise, decoder's memory is exhausted while processing.

dc82ccb9a2 msdk: context: add job type to figure out if joining session is necessary
According to the driver's instruction, if there are two or more encoders
or decoders in a process, the session should be joined by
MFXJoinSession.

To achieve this successfully by GstContext, this patch adds job type
specified if it's encoder, decoder or vpp.

If a msdk element gets to know if joining session is needed by the
shared context,
it should create another instance of GstContext with joined session,
which
is not shared.

4d860ec82b msdk: adds frame allocator using libva
Implements msdk frame allocator which is required from the driver.
Also makes these functions global so that GstMsdkAllocator could use
the allocated video memory later and couple with GstMsdkMemory.

GstMsdkContext keeps allocation information such as mfxFrameAllocRequest
and mfxFrameAllocResponse after allocation.

6ce9a66b80 msdk: implements GstMsdkContext.
Makes GstMsdkContext to be a descendant of GstObject so that
we could track the life-cycle of the session of the driver.

Also replaces MsdkContext with this one.
Keeps msdk_d3d.c alive for the future.
