utils: raspberrypi: ctt: Fix NaNs in chromatic aberration tables

NaNs can appear if no black dots can be found and analysed in a
particular region of the calibration image. There needs to be at least
one such dot in every 8x8 cell covering the image.

This is now detected, and an error message issued. No CAC tables are
generated, so CAC is disabled.

libcamera v0.5.0

The abi-compliance-checker reports there are both ABI and API changes in this
release:

  Binary compatibility: 99%
  Source compatibility: 99.5%
  Total binary compatibility problems: 5, warnings: 1
  Total source compatibility problems: 6, warnings: 1

Substantially less than the previous release, and ultimately quite minor but
unfortunately there nonetheless and so the SONAME is updated to 0.5
accordingly. I do not anticipate anything there that cannot be solved for
applications without just a recompile. I had hoped to get a longer run for 0.4
series...

A full and detailed ABI report for those interested can always be generated
between any two versions with the internal tooling:

 "./utils/abi-compat.sh v0.4.0 v0.5.0"

Integration overview:

This release brings in 201 commits with a huge list of fixes and code clean up
which I'm very happy to see, including interesting fixes to the AGC and AWB
handling in libipa.

In regards to new features, libcamera-0.5 has aptly now got the core Raspberry
Pi 5 support merged!. There are still patches that are currently maintained by
Raspberry Pi for additional features, and while the transition to upstream
API's continue, but I think we're all happy to see this support getting in
directly, and Raspberry Pi continue to lead the way in upstream camera
development. I look forward to the kernel API's for streams being fully
utilised by the PiSP platform for upstream camera metadata handling. This
upcoming work is also supported by the CameraSensor factory and CameraSensorRaw
support that is now also merged in this release.

Further more in the platform support, the software_isp continues to be
developed and is now able to measure colour temperature, which will bring in
improvements for AWB, and a CCM can be applied while peforming debayering (at a
CPU cost) which will allow us to finally apply color tuning for sensors on
devices that need to fall back to the software ISP.

New sensor support seems fairly short in this release, with the IMX415 being
the prominent addition.

In libipa, and algorithm developments, along with many fixes and improvements
there is a substantial new feature that the Baysian AWB algorithm from
Raspberry Pi can now also be used on all libipa supported IPA modules, and has
shown good impovements for the RkISP1 supported devices.

There is minimal changes to the application support side, but it is notable
that now the Y444 format has been mapped to be usable by the gstreamer src
element. lc-compliance has seen some progress which I hope will bring this to
being a more central part of the test infrastructure.

improvement to an existing commit.

ipa: rpi: Fix incorrect cast for ExposureTime ControlInfo

controls::ExposureTime is of type ControlTypeInteger32, but the
default ControlInfoMap casts a value to int64_t causing incorrect
initialisation of the associated ControlInfo.

Fix this by casting correctly to int32_t.

ipa: rpi: Apply default ControlInfo values for sensor controls (2)

Unfortunately the previous fix for default sensor ControlInfo values was

the ConrolInfo during ipa::init() are present. Fix this.

ipa: rpi: Apply default ControlInfo values for sensor controls

The existing IPA initialisation code did not set default values for
some sensor related controls. This caused a crash using libcamerify
when the it was trying to access the default value for
controls::FrameDurationLimits as part of a recent change.

Ensure controls::FrameDurationLimits, controls::AnalogueGain and
controls::ExposureTime advertise default values along with the existing
min/max values. The default is set to the defaults defined in the IPA
set during initialisation.

libcamera v0.4.0

The abi-compliance-checker reports that there is both ABI and API breakage in
this release.

  Binary compatibility: 91.2%
  Source compatibility: 98.9%
  Total binary compatibility problems: 69, warnings: 0
  Total source compatibility problems: 9, warnings: 0

This is not too surprising as this was the reason for the extra delay holding
up this release, and as such this release bumps the SONAME to 0.4 accordingly.

The majority of the ABI breakages are around the public API for Control
handling and definitions, which have caused underlying identifiers to be
changed, and the reuqired storage for controls has increased.

I hope that grouping the expected ABI and API breakages and delaying this
release will allow a longer stability on the 0.4 series but as we are
developing rapidly this can not be guaranteed, though we aim to minimise
disruption to distributions and applications whereever possible.

This release brings in 253 commits, with substantial development on image
control and tuning features for IPA and Pipeline handlers supporting libipa, as
well as integrating libipa support for IPA handling on the ARM Mali-C55 ISP.

A new 'Virtual Pipeline Handler' has been introduced to support more testing in
CI and virtual environments.

Gstreamer has had some interesting development to rework expressing the full
control set from libcamera using auto generation from the full control
descriptors.

A key and notable change in this release too is that the softISP is now moving
towards utilising the libipa implementaitons which will enable future tuning
and image control capabilities, and should also support future development on a
GPU-ISP implementation for GPU-accelerated handling. I do believe this work may
have introduced an oscillation regression in the AEGC which will need to be
investigated and fixed in the near future, but I don't want to hold up
progressing the ABI updates at this stage.

The i.MX8MP can now make full use of the DW100 Dewarp Engine for full rotation
and digital zoom capabilities.

Raspberry Pi systems now have improved support for the OV7251, IMX462, and
IMX327 Sensors, and libipa platforms can now make use of the GalaxyCore gc05a2
and gc08a3 Image sensors.

ipa: rpi: awb: Disable CT search bias for Grey World AWB

If grey world AWB is setup in the tuning file, the CT curve will either
be missing or invalid. Disable biasing the statistics for the search in
such cases.
