a00ae0918a plugins: cope with new GstVaapiVideoMeta API. 
Update plugin elements with the new GstVaapiVideoMeta API.

This also fixes support for subpictures/overlay because GstVideoDecoder
generates a sub-buffer from the GstVaapiVideoBuffer. So, that sub-buffer
is marked as read-only. However, when comes in the textoverlay element
for example, it checks whether the input buffer is writable. Since that
buffer read-only, then a new GstBuffer is created. Since gst_buffer_copy()
does not preserve the parent field, the generated buffer in textoverlay
is not exploitable because we lost all VA specific information.

Now, with GstVaapiVideoMeta information attached to a standard GstBuffer,
all information are preserved through gst_buffer_copy() since the latter
does copy metadata (qdata in this case).

df1eb6e01e vaapiupload: reset direct-rendering to zero when changing caps. 
Make sure to reset direct-rendering flag to zero when caps are changed,
and only derive it to one when the next checks succeed.

d4a4a49168 vaapisink: compute and expose the supported set of YUV caps. 
Make vaapisink expose only the set of supported caps for raw YUV buffers.

Add gst_vaapi_uploader_get_caps() helper function to determine the set
of supported YUV caps as source (for images). This function actually
tries to zero and upload each image to a 64x64 test surface. Of course,
this relies on VA drivers to not claim success if vaPutImage() is not
correctly supported.

499e0dd981 vaapisink: add support for raw YUV buffers. 
Add new GstVaapiUploader helper to upload raw YUV buffers to VA surfaces.
It is up to the caller to negotiate source caps (for images) and output
caps (for surfaces). gst_vaapi_uploader_has_direct_rendering() is available
to help decide between the creation of a GstVaapiVideoBuffer or a regular
GstBuffer on sink pads.
