qemu: Introduce a new graphics display type 'headless'
Since 2.10 QEMU supports a new display type egl-headless which uses the
drm nodes for OpenGL rendering copying back the rendered bits back to
QEMU into a dma-buf which can be accessed by standard "display" apps
like VNC or SPICE. Although this display type can be used on its own,
for any practical use case it makes sense to pair it with either VNC or
SPICE display. The clear benefit of this display is that VNC gains
OpenGL support, which it natively doesn't have, and SPICE gains remote
OpenGL support (native OpenGL support only works locally through a UNIX
socket, i.e. listen type=socket/none).

qemu: caps: Introduce a capability for egl-headless
Since QEMU 2.10, it's possible to use a new type of display -
egl-headless which uses drm nodes to provide OpenGL support. This patch
adds a capability for that. However, since QEMU doesn't provide a QMP
command to probe it, we have to base the capability on specific QEMU
version.

examples: Add clean-traffic-gateway into nwfilters
The filter purpose is to simulate isolated private VLAN.
The behavior can be achieved by limiting network traffic
to traffic between VM and gateway. Because there is no
concept of the PVLAN in the linux bridge.
The filter also contains parts from clean-traffic
to prevent VM from spoofing its IP and MAC address.
To use this filter the user just needs to set
the GATEWAY_MAC variable to gateway MAC address.
