Demo instrument cluster receiver application to receive a h264 stream sent via RTP from another host running Wayland and Weston with the gst-recorder feature for streaming a virtual display patched in. The gstreamer pipeline used is based on what was being used with gst-launch-1.0 in the previously hand-constructed instrument cluster demo. The use of vaapisink likely constrains use to Intel based platforms at present, future work should allow working on other platforms. The app/surface.{hpp,cpp} files are adapted from code from xdg-launcher: https://gerrit.automotivelinux.org/gerrit/staging/xdg-launcher Note that they are MIT licensed while all other source files are Apache 2.0. Other than significant refactoring to ease integration, the functional differences from the runxdg code in xdg-launcher are that homescreen support has been removed, as the instrument cluster platform does not use it, and the logging has been reworked to use the hmi-debug mechanism used by the windowmanager and homescreen. There is also an implicit assumption that the windowmanager configuration is such that the "app" role will map the receiver's surface to the desired location in the center of the dashboard.
