2022-09-28ipa: rkisp1: Convert to use the FCQueueKieran Bingham
Establish a queue of FrameContexts using the new FCQueue and use it to supply the FrameContext to the algorithms. The algorithms on the RKISP1 do not use this yet themselves, but are able to do so after the introduction of this patch.

2022-09-28ipa: rkisp1: Rename frameContext to activeStateKieran Bingham
The RkISP1 IPA module creates a single instance of its IPAFrameContext structure, effectively using it more as an active state than a per-frame context. To prepare for the introduction of a real per-frame context, move all the members of the IPAFrameContext structure to a new IPAActiveState structure. The IPAFrameContext becomes effectively unused at runtime, and will be populated back with per-frame data after converting the RkISP1 IPA module to using a frame context queue. The IPAActiveState structure will slowly morph into a different entity as individual algorithm get later ported to the frame context API. While at it, fix a typo in the documentation of the Agc::computeExposure() function that incorrectly refers to the frame context instead of the global context.

2022-06-29ipa: libipa: Introduce a Module class templateLaurent Pinchart
libipa defines an abstract Algorithm class template that is specialized by IPA modules. IPA modules then instantiate and manage algorithms internally, without help from libipa. With ongoing work on tuning data support for the RkISP1, and future similar work for the IPU3, more code duplication for algorithms management is expected. To address this and share code between multiple IPA modules, introduce a new Module class template that will define and manage top-level concepts for the IPA module. The Module class template needs to be specialized with the same types as the Algorithm class. To avoid manual specialization of both classes, store the types in the Module class, and replace the template arguments of the Algorithm class with a single Module argument from which the other types are retrieved.
