5f770f748c libcamera: Make converter/softISP configure()'s outputCfgs argument really const
The intent of the outputCfgs argument to the configure() function of
converter classes and the softISP is to allow the passed in stream-configs
to not be changed.

But only the vector is const, the reference inside the vector are not
const, which allows modifying the stream-configs as can be seen inside
DebayerEGL::configure() which was using a non const reference outputCfg
helper variable.

Fix this by making the references inside the vector const.

As shown by commit 94d32fdc55 ("pipeline: simple: Consider output sizes

Benchmark results for the Arduino Uno-Q with a weak CPU which is good for

3280x2464 -> 3272x2464:

1 thread : 147ms / frame, ~6.5 fps
2 threads:  80ms / frame, ~12.5 fps
3 threads:  65ms / frame, ~15 fps

Adding a 4th thread does not improve performance.

78b9890a0f libcamera: software_isp: debayer: Take DebayerParams by ref
When calling `Debayer::process()` from `SoftwareIsp::process()`, the
`DebayerParams` object is copied multiple times:

  (1) call of `BoundMethodMember<...>::activate()`
      inside `Object::invokeMethod()`
  (2) constructor of `BoundMethodArgs<...>`
      inside `BoundMethodMember<...>::activate()`
  (3) call of `BoundMethodMember<...>::invoke()`
      inside `BoundMethodArgs::invokePack()`
  (4) call of the actual pointer to member function
      inside `BoundMethodMember::invoke()`

While compilers might avoid one or two of the above copies, this is still
not ideal. By making `Debayer::process()` take the parameter object by
const lvalue reference, only the copy in the `BoundMethodArgs` constructor
remains. So do that.

60f150bf87 libcamera: ipa: simple: Disable Ccm algorithm by default again
The default CCM in uncalibrated.yaml is just an identity transformation
and has been enabled by default only to always provide a correction
matrix to GPU ISP.  It slows down CPU ISP when CCM is not used.

Now, when a default correction matrix is always provided to GPU ISP, we
can disable the Ccm algorithm in uncalibrated.yaml again.  The check for
ccmEnabled in GPU ISP is no longer needed and it must be removed in
order not to fail when Ccm algorithm is not enabled.  ccmEnabled flag is
still needed in CPU ISP where the processing differs based on whether
CCM is present or not.

3ffaa4c0e2 libcamera: ipa: simple: Remove Lut algorithm
The Lut algorithm is not really an algorithm.  Moreover, algorithms may
be enabled or disabled but with Lut disabled, nothing will work.

Let's move the construction of lookup tables to CPU debayering, where it
is used.  The implied and related changes are:

- DebayerParams is changed to contain the real params rather than lookup
  tables.
- contrastExp parameter introduced by GPU ISP is used for CPU ISP too.
- The params must be initialised so that debayering gets meaningful
  parameter values even when some algorithms are disabled.
- combinedMatrix must be put to params everywhere where it is modified.
- Matrix changes needn't be tracked in the algorithms any more.
- CPU debayering must watch for changes of the corresponding parameters
  to update the lookup tables when and only when needed.
- Swapping red and blue is integrated into lookup table constructions.
- gpuIspEnabled flags are removed as they are not needed any more.

07240afa12 libcamera: simple: Fix black level offsets in AWB
The black level offset subtracted in AWB is wrong.  It assumes that the
stats contain sums of the individual colour pixels.  But they actually
contain sums of the colour channels of larger "superpixels" consisting
of the individual colour pixels.  Each of the RGB colour values and the
computed luminosity (a histogram entry) are added once to the stats per
such a superpixel.  This means the offset computed from the black level
and the number of pixels should be used as it is, not divided.

The patch fixes the subtracted offset.  Since the evaluation is the same
for all the three colours now, the individual class variables are
replaced with a single RGB variable.

Fixes: 4e13c6f55b ("Honor black level in AWB")

0c2ed9ebf9 egl: Use the Mesa surfaceless platform instead of GBM
Mesa surfaceless platform appears to be a better fit for the use-case at hand:
1. Like GBM it is Mesa specific, so no change in supported setups is
   expected. If ever required, a fallback to the generic device platform
   could be added on top.
2. It leaves the complexity of selecting a renderer device to the
   driver, reducing code and dependencies.
3. It allows to use llvmpipe / software drivers without dri device,
   which can be useful on CI or debugging (with LIBGL_ALWAYS_SOFTWARE=1).

7e72e84f3d libcamera: software_isp: Add member variables to track selected input/output pixelFormat
In order to have Debayer::start() tell the eGL shader compilation routine what
the input and output pixel format is, we need to have a copy of the
selected format available. Add variables to the inputConfig and
outputConfig structures to allow tracking of this data for later use.

4cb388a1eb libcamera: software_isp: debayer: Introduce a start() / stop() methods to the debayer object
In order to initialise and deinitialise gpuisp we need to be able to setup
EGL in the same thread as Debayer::process() happens in.

This requires extending the Debayer object to provide start and stop
methods which are triggered through invokeMethod in the same way as
process() is.

Introduce start() and stop() methods to the Debayer class. Trigger those
methods as described above via invokeMethod. The debayer_egl class will
take care of initialising and de-initialising as necessary. Debayer CPU
sees no functional change.

Per feedback from Barnabas the stop method is using blocking
synchronisation and thus we drop ispWorkerThread_.removeMessages().

LookupTable and redCcm_.
