Bug 1151 - Working OculusVR SDK 0.5.0.1 on GNU/Linux w/ Positional Tracker (DK2)

Note: The ovrd server must run, otherwise no device is being detected.

General Stereo API Changes:
  - EyePose -> ViewerPose

    - We only use the viewer pose and derive the pupile position
      via EyeParameter.

    - Hence we reduce complexity.

    - A single ViewerPose will be maintained by StereoDeviceRenderer

    - position is in meter, allowing StereoGLEventListener to scale
      device independent.

  - StereoDevice receives knowledge of certain sensors,
    to be queried and used for start-sensors.

OVR:
  - Simply apply the above general changes

  - Build: Remove [more] unused API entries for SDK rendering
