The libipa.cpp file exists for the sole purpose of documentating the ipa
namespace. As we now have a top-level module.cpp file in libipa, move
the documentation there, and drop libipa.cpp.

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 ScalerCrop control is handled directly by the pipeline handler. Remove the
control from the IPA's static ControlInfoMap, and let the pipeline handler add
it to the ControlInfoMap advertised to the application, ensuring the limits
are set appropriately based on the current sensor mode.

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.

When a request completes, a debug message is generated to help
identify the request and the number of streams it contains.
The printed number of streams is however the number of output buffers
requested by the camera framework, not the number of streams generated
by libcamera. In facts, some output buffers are generated by
post-processing, and not directly from the camera.
As the debug message prints the libcamera identifier for the Request, it
is more logical to print the number of streams generated by the camera
instead of the total number of streams.

Mapped streams are generated by post-processing and always require a
source buffer to process image data from.
In case a Mapped stream is requested but its source stream is not, it
is required to allocate a buffer on the fly and add it to the

Make sure a source stream is available for all mapped streams, and if
that's not the case, add a dedicated buffer to the request for that
purpose.

We always call CameraManager.read_event() and
CameraManager.get_ready_requests(), so to simplify the use merge the
read_event() into the get_ready_requests().
This has the side effect that get_ready_requests() will now block if
there is no event ready. If we ever need to call get_ready_requests() in
a polling manner we will need a new function which behaves differently.
However, afaics the only sensible way to manage the event loop is to use
select/poll on the eventfd and then call get_ready_requests() once,
which is the use case what the current merged function supports.
