When AFTrigger is received, AF algorithm internal state is reset to
initial values. If reset happens between frames, then first contrast
value that arrives after this, is interpreted as contrast for initial
position. This is wrong, because it was measured for lens position
before the reset. Skip this first frame to allow correct contrast
measure for the initial lens position.

Rockchip ISP AF block allows calculation of sharpness and luminance
in up to three user defined windows. If no windows are set, there are
some default settings applied for the first window and exposed through
the driver. For each frame, use the sharpness value calculated for this
default window and feed the hill climbing algorithm with them. Then set
the lens position to value calculated by the algorithm.

In order to allow dynamic instantiation of algorithms based on tuning
data files, add a mechanism to register algorithms with the IPA module.
The implementation relies on an AlgorithmFactory class and a
registration macro, similar to the pipeline handler registration
mechanism. The main difference is that the algorithm registration and
instantiation are implemented in the Module class instead of the
AlgorithmFactory class, making the factory an internal implementation
detail.

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.

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().

Currently the pipeline handler advertises controls handled by the IPA from a
static ControlInfoMap defined in the raspberrypi.h header. This change removes
this header file, and instead the IPA returns the ControlInfoMap to the pipeline
handler from the ipa::init() function. This is done to allow the IPA to adjust
the limits of the controls based on the sensor mode in a subsequent change.

Instead of having one frame context constantly being updated,
this patch aims to introduce per-frame IPAFrameContext which
are stored in a ring buffer. Whenever a request is queued, a new
IPAFrameContext is created and inserted into the ring buffer.
The IPAFrameContext structure itself has been slightly extended
to store a frame id and a ControlList for incoming frame
controls (sent in by the application). The next step would be to
read and set these controls whenever the request is actually queued
to the hardware.
Since now we are working in multiples of IPAFrameContext, the
Algorithm::process() will actually take in a IPAFrameContext pointer
(as opposed to a nullptr while preparing for this change).

Currently we have a single structure of IPAFrameContext but
subsequently, we shall have a ring buffer (or similar) container
to keep IPAFrameContext structures for each frame.
It would be a hassle to query out the frame context required for
process() (since they will reside in a ring buffer) by the IPA
for each process. Hence, prepare the process() libipa template to
accept a particular IPAFrameContext early on.
As for this patch, we shall pass in the pointer as nullptr, so
that the changes compile and keep working as-is.

Currently, IPAFrameContext consolidates the values computed by the
active state of the algorithms, along with the values applied on
the sensor.
Moving ahead, we want to have a frame context associated with each
incoming request (or frame to be captured). This shouldn't necessarily
be tied to "active state" of the algorithms hence:
- Rename current IPAFrameContext -> IPAActiveState
This will now reflect the latest active state of the algorithms and
has nothing to do with any frame-related ops/values.
- Re-instate IPAFrameContext with a sub-structure 'sensor' currently
storing the exposure and gain value.
Adapt the various access to the frame context to the new changes
as described above.
Subsequently, the re-instated IPAFrameContext will be extended to
contain a frame number and ControlList to remember the incoming
request controls provided by the application. A ring-buffer will
be introduced to store these frame contexts for a certain number
of frames.

The IPAIPU3 interface currently uses event-type based structures in
order to communicate with the pipeline-handler (and vice-versa).
Replace the event based structures with dedicated functions associated
to each operation.
The translated naming scheme of actions to signals are:
ActionSetSensorControls => setSensorControls
ActionParamFilled => paramsBufferReady
ActionMetadataReady => metadataReady
The translated naming scheme of events to dedicated functions are:
EventProcessControls => queueRequest()
EventStatReady => processStatsBuffer()
EventFillParams => fillParamsBuffer()
The dedicated functions are called from pipeline-handler to the IPA
using IPC. These functions run asynchronously and when completed,
the IPA emits the respective signals as stated above in the translated
naming scheme.
The EventProcessControls is translated to queueRequest() to bring
symmetry to the IPU3 interface with other IPA interfaces.
