ipa: raspberrypi: Use an array of RPiController::Metadata objects
Allow the IPA to cycle through an array of RPiController::Metadata objects, one
per prepare()/process() invocation, when running the controller algorithms. This
allows historical metadata objects to be retained, and subsequently passed into
the controller algorithms on future frames. At present, only a single index into
this array is used.
This change provides a route to fixing a problem with the AGC algorithm, where
if a manual shutter/gain is requested, the algorithm does not currently retain
any context of the total exposure that it has calculated. As a result, the
wrong digital gain would be applied when the frame with the manual shutter/gain
is processed by the ISP.
