2023-02-09	ipa: raspberrypi: Use the generic statistics structure in the algorithms	Naushir Patuck
	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.

2023-02-09	ipa: raspberrypi: Generalise statistics	Naushir Patuck
	At present, the controller algorithms access the bcm2835_isp_stats structure, which is hardware specific. It would be desirable to abstract out the statistics structure to remove hardware specific headers from the algorithms source files. Define a new templated RegionStats class that encompasses region based statistics generated by the ISP. For the VC4 ISP, this can be used to hold RGB sums and focus FoM values. Define a new Statistics structure that holds all the VC4 ISP statistics output. This includes AGC histograms, AGC/AWB region sums and focus FoM regions.
