608ce681e5 libs: surface: port to GstMiniObject
GstVaapiMiniObject and GstVaapiObject are deprecated.

This is the first step to remove them by porting GstVaapiSurface as
a GstMiniBuffer descendant.

4505acc522 libs: remove dependency on IN_LIBGSTVAAPI_CORE
This conditional code was when libgstvaapi was intended to be library
used outside GStreamer. This not the case anymore, thus removing it.

7fc1b70ff6 libs: bufferproxy: gst_vaapi_buffer_proxy_{set,peek}_mem()
This patch adds a GstMemory as a variable member of the buffer proxy,
because we will need to associate the buffer proxy with the memory
which exposes it. Later, we will know which memory, in the video buffer
pool, is attached to the processed surface.

38f8fea4bb guard buffer export API if not available
The support for buffer exports in VA-API was added in version 0.36. These
interfaces are for interop with EGL, OpenCL, etc.

GStreamer-VAAPI uses it for a dmabuf memory allocator. Though, gstreamer-vaapi
has to support VA-API versions ranging from 0.30.4, which doesn't support it.

This patch guards all the buffer exports handling (and dmabuf allocator) if
the detected VA-API version is below 0.36.

250260cc36 Add abstraction for exported VA buffers.
The VA buffer export APIs work for a particular lifetime starting from
vaAcquireBufferHandle() and ending with vaReleaseBufferHandle(). As such,
it could be much more convenient to support implicit releases by simply
having a refcount reaching zero.
