In order to enable, in the future, dmabuf-based buffers, the vaapi base plugin needs to check if downstream can import dmabuf buffers. This patch checks if downstream can handle dmabuf, by introspecting the shared GL context. If the GL context is EGL/GLES2 and have the extension EGL_EXT_image_dma_buf_import, then dmabuf can be negotiated. Original-patch-by: Julien Isorce <j.isorce@samsung.com>
