Fix a bug in the IPA frame dropping (for rate control) logic, where the metadata for the current context was copied from itself (i.e. a no-op), instead of being copied from the previous context. This bug does not occur in normal conditions, only when running with a low exposure time and unconstrained framerate, which happens in a particular picamera2 test.

2022-11-29ipa: raspberrypi: agc: Fix digital gain calculation for manual modeNaushir Patuck
The digital gain calculation uses a total exposure value computed with the current AGC state. However, this is wrong in the case of manual shutter/gain controls, as the total exposure value used must be the value computed when the AGC sent the manual shutter/gain controls to the pipeline handler to action. To fix this, the IPA now adds the historical AgcStatus structure to the metadata (tagged with "agc.delayed_status"). This historical AgcStatus structure contains the total exposure value calculated when the AGC sent the manual shutter/gain controls to the pipeline handler.

2022-11-29ipa: raspberrypi: Use an array of RPiController::Metadata objectsNaushir Patuck
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.

The ipa currently advertises a static ControlInfoMap to specify the available controls and their limits. Fix this limitation by having the IPA populate a new ControlInfoMap with updated limits for ExposureTime, AnalogueGain, and FrameDurationLimits controls based on the current sensor mode. This new ControlInfoMap is then returned back to the pipeline handler and available to the application after a successful Camera::configure() call. Before the first call to Camera::configure(), this ControlInfoMap provides some reasonable default limits for ExposureTime, AnalogueGain, and FrameDurationLimits. However, applications must not rely on these values, but obtain the correct limits after the call to Camera::configure().
