2023-05-09meson: Fix usage of overwritten pipeline variableLaurent Pinchart
When iterating over enabled pipelines and IPA modules, libcamera descends into subdirectories in a recursive manner, which involves nested loops. Both the outer and inner loops use the same loop variable named 'pipeline'. As the outer loop uses the variable after descending into the inner directory, it ends up using an incorrect value. Fix it by moving all use of the variable before the subdir() call, and add a comment that warns about the issue to avoid reintroducing it.

Create a new PipelineHandlerBase class that handles general purpose housekeeping duties for the Raspberry Pi pipeline handler. Code the implementation of new class is essentially pulled from the existing pipeline/rpi/vc4/raspberrypi.cpp file with a small amount of refactoring. Create a derived PipelineHandlerVc4 class from PipelineHandlerBase that handles the VC4 pipeline specific tasks of the pipeline handler. Again, code for this class implementation is taken from the existing pipeline/rpi/vc4/raspberrypi.cpp with a small amount of refactoring. The goal of this change is to allow third parties to implement their own pipeline handlers running on the Raspberry Pi without duplicating all of the pipeline handler housekeeping tasks.

The existing mechanism of setting a timeout value simply uses the maximum possible frame length advertised by the sensor mode. This can be problematic when, for example, the IMX477 sensor can use a frame length of over 600 seconds. However, for typical usage the frame length will never go over several 100s of milliseconds, making the timeout very impractical. Store a list of the last 10 frame length values requested by the AGC. On startup, and at the end of every frame, take the maximum frame length value from this list and return that to the pipeline handler through the setCameraTimeoutValue() signal. This allows the timeout value to better track the actual sensor usage.

2023-01-30ipa: raspberrypi: Add lens position to DeviceStatusNaushir Patuck
Add the current frame's lens position (in dioptres) to the DeviceStatus structure. This value is obtained from the AfAlgorithm::getLensPosition() member function. Return this lens position back to the pipeline handler to store in the metadata field of the request. As a drive-by, fixup some inaccurate comments in the DeviceStatus structure.

2023-01-30ipa: raspberrypi: First version of autofocus algorithm using PDAFNick Hollinghurst
Provide the first version of the Raspberry Pi autofocus algorithm. This implementation uses a hybrid of contrast detect autofocus (CDAF) and phase detect autofocus (PDAF) statistics. PDAF is always preferred over CDAF due to having less "hunting" behavior.
