Added a feature to use accelerometer data to rotate camera view in software when the camera is physically rotated such that the view on the screen is always upright even when the camera is upside down. Enabling it, and disabling it is done with the "r" key. Not on by default. I enabled several things that were disabled in the last patch, but only when rotation mode is toggled on.

Added api to set chunk processing callbacks on depth and video streams. These enable bypassing the costly memcpy in stream_process().You can find a demo of the functionality in examples/chunkview.c that unpacks the frame on the fly and downsamples it to 320x240. Testing indicates that the overhead of getting a 320x240 frame, unpacked and converted to mm(passing a lookup table through dev->user_data) is roughly the same as getting the packed 640x480 frame. Thresholding could also be applied in the callback for even more gains etc.
