fbbf9c629a va: allocator: add _set_format() and _get_format()
Since allocators keep an available memory queue to reuse, video format and usage
hint are now persistant while allocator's memories are around.

This patch adds _set_format() and _get_format() for both VA allocators.

_set_format() validates if given format can be used or reused. If no allocated
surface previously it creates a dummy one to fetch its offsets and
strides. Updated info is returned to callee.

GstVaPool uses _set_format() at config to verify the allocator capacity and to
get the surfaces offsets and strides, which are going to be used by the video
meta.

Allocator extracted caps are compared with caps from config and if they have
different strides or offsets, force_videometa is set.

A new bufferpool method gst_va_pool_requires_video_meta() is added return the
value of force_videometa. This value is checked in order to know if decoders
need to copy the surface if downstream doesn't announce video meta support.

67eb0a9440 va: remove GstVideoInfo parameter from _get_surface() functions
There shouldn't be need to retrieve GstVideoInfo per buffer or memory since it
is the same for all the negotiated stream.

64eb0f0ed2 va: dec, vpp: don't get buffer size from allocators
Since buffer size is now ignored by bufferpool there's no need to get tha value
from the allocator.

666eedc215 va: caps: centralize caps feature discovering
These function were repeated in the different implemented
elements. This patch centralize them.

The side effect is dmabuf memory type is no longer checked with the
current VAContext, but assuming that dmabuf is a consequence of caps
negotiation from dynamic generated caps templates, where the context's
memory types are validated, there's no need to validate them twice.

990d1bfbce va: vpp: global lock to handle shared buffers
Add a global mutex to exclusive access to shared stream buffers, such
as DMABufs or VASurfaces after a tee:

LIBVA_DRIVER_NAME=iHD \
gst-launch-1.0 v4l2src ! tee name=t t. ! queue ! \
  vapostproc skin-tone=9 ! xvimagesink \
  t. ! queue ! vapostproc ! xvimagesink

Video postprocessor for VA-API

Funcionalities: resize frames, change format, import buffers, apply
filters (such as denoise, sharpen, orientation, if driver offers them).
