Repurpose the StatisticsPtr type from being a shared_ptr<bcm2835_isp_stats> to shared_ptr<RPiController::Statistics>. This removes any hardware specific header files and structures from the algorithms source code. Add a new function in the Raspberry Pi IPA to populate the generic statistics structure from the values provided by the hardware in the bcm2835_isp_stats structure. Update the Lux, AWB, AGC, ALSC, Contrast, and Focus algorithms to use the generic statistics structure appropriately in their calculations. Additionally, remove references to any hardware specific headers and defines in these source files.
