Install a new video converter that supports X11 pixmap targets for X11
backends only, or make the GLX converter creation function chain up to
the X11 converter whenever requested.
Implement GstSurfaceMeta API for GStreamer 1.0.x. Even though this is
an unstable/deprecated API, this makes it possible to support Clutter
sink with minimal changes. Tested against clutter-gst 1.9.92.
Port vaapidecode and vaapisink plugins to GStreamer API >= 1.0. This
is rather minimalistic so that to test the basic functionality.
Disable vaapiupload, vaapidownload and vaapipostproc plugins. The latter
needs polishing wrt. to GStreamer 1.x functionality and the former are
totally phased out in favor of GstVaapiVideoMemory map/unmap facilities,
which are yet to be implemented.

Add new gst_vaapi_video_buffer_new() helper function that allocates a video
buffer from a GstVaapiVideoMeta. Also remove obsolete and useless function
gst_vaapi_video_buffer_get_meta().
