Build: Add XCB_LIBS; Skeleton: mlo_initializeInd, mlo_attachDeviceReq

* Renamed some of the Sense API lib classes
  (CSensorDeviceDesc=>CSenseDeviceDesc,
  SensorDeviceDesc=>SenseDeviceDesc).
* Moved SenseApiDesc into /include/user/senseApiDesc.
* Add conversion constructor to convert from SenseDeviceDesc
  to
* Wireframe mlo_initializeInd to call xcb_connect().
* Add $(XCB_LIBS) to libxcbXorg_LDFLAGS.
* Wireframe mlo_attachDeviceReq().
