Patched MMU so that it works for kernel-space adresses (bypass MMU)
this patch was proposed by Daniel Borkmann
added pcores to transform YCbCr to RGB color space and back
added new protocol graph demo, where a hardware functional block
captures compressed version of video frames (from the hdmi in
interface of an FMC module) and sends them over the phsical
ETH interface.

Current status: a central GUI can display the frames of multiple
'smart cameras'.

ToDo: integrate object tracking in a single camera, tracking handover
      further protocols, protocol adaptation strategies
      and support for partial reconfiguration.
