There are valid cases where a module returns None. E.g. no images were
provided for LSC calibration. We should however define proper semantics
there. Continue with a warning for now.

In the tuning datasets, the files had names like
'imx335_1600l_3000k_1.dng'. That failed on the old filename parsing

Port commit 66479605baca ("utils: raspberrypi: ctt: Improve the Macbeth

Previously the code would brighten up images in case the Macbeth Chart
is slightly dark, and also zoom in on sections of it to look for
charts occupying less of the field of view. But it would not do both
together.
This change makes the search for smaller charts also repeat that
search for the brightened up images that it made earlier, thereby
increasing the chances of success for non-optimal tuning images.

Move black levels for tuning files that contained a BLC block into
the camera sensor helpers.
ov4689.yaml had 66@12bit while the datasheet states 64@12bit. Use the
value from the datasheet (scaled to 16bit).
ov5640.yaml had 256@12bit while the datasheet states 16@10bit. Looking
at the commit message the 256 most likely stems from the imx219 tuning
file and 16@10bit is the same as the 64@12bit from the ov4689. This
seems more likely and is therefore used.

As the camera sensor helper now has the ability to provide the black
level, use it. Black levels can still be overwritten by the tuning
file, but the direction is to remove them from the tuning files and move
them into the sensor helpers.
Additionally interpret all values based on 16bits. The conversion to the
scale required by the hardware is done in process(). It ensures all the
values inside libcamera are the same scale and is in preparation for the
i.MX8MP where black levels are based on a 20bit scale. Note that this
breaks existing tuning files. The tuning files distributed with
libcamera will be fixed in a later patch.

The converter interface uses the unsigned int output stream index to map
to the output frame buffers. This is cumbersome to implement new
converters because one has to keep around additional book keeping
to track the streams with their correct indexes.
The v4l2_converter_m2m and simple pipeline handler are adapted to
use the new interface. This work roped in software ISP as well,
which also seems to use indexes (although it doesn't implement converter
interface) because of a common conversionQueue_ queue used for
converter_ and swIsp_.
The logPrefix is no longer able to generate an index from a stream, and
is updated to be more expressive by reporting the stream configuration
instead, for example, reporting "1920x1080-MJPEG" in place of
"stream0".

The streams sanity check tries to determine if all the stream indexes
passed in outputs std::map<> are unique. However, since the data
container is std::map<>, all its keys (stream indexes in this case),
are already unique.
Instead, rectify the sanity check to ensure all the framebuffers passed
in the outputs std::map<> are unique to each index. Hence, no two stream
indexes should have same framebuffer. Update the comment to reflect

The ipaCreate() function is the entry point to IPA modules. It is
declared in ipa_interface.h, and defined by each module. As the function
is defined with extern "C" linkage, the namespace in which it is
contained is not very relevant from a caller's point of view. For the
IPA module implementer, however, defining the function in the libcamera
namespace avoids adding an explicit libcamera:: prefix to the symbols
used by the function. This is why all IPA modules define their
ipaCreate() entry point in the libcamera namespace.
The ipa_interface.h file, however, declares the function in the global
namespace. This doesn't cause any issue at runtime, but will cause a
missing declaration warning when we enable them. To prepare for that,
move the function declaration to the libcamera namespace.
