This patch series adds options to select a preferred codec and also
to forward a dmabuf directly to the encoder module that is part of
the Spice server. Currently, gstreamer:h264 is the only combination
tested but additional work is ongoing to test other combinations.
Tested with: -device virtio-gpu-pci,max_outputs=1,blob=true,xres=1920,yres=1080
-spice port=3001,gl=on,disable-ticketing=on,dmabuf-encode=on,
preferred-codec=gstreamer:h264
and remote-viewer --spice-debug spice://x.x.x.x:3001 on the client side.

v2:
- Used the already available gl_scanout and gl_draw_async APIs instead
of adding new ones to Spice.
- Improved the commit message of the second patch
