Update cameraHAL to use CM7 libcamera.so, linking directly to it. QCamera_Intf.h and CameraHardwareInterface.h have been updated as best I can tell the blob needs them. QualcommCameraHardware.cpp has been modified to build, but doesn't seem to work for unknown reasons, and isn't used.
Forgot readme in last commit
