The libcamera::Rectangle class allows defining rectangles regardless of
the orientation of the reference system where a rectangle is used in.
This implies that, depending on the reference system in use, the
rectangle's top-left corner, as defined by libcamera, doesn't correspond
to the visual top-left position.

When constructing a ControlValue from an enum value, an explicit cast to
int32_t is needed as we use int32_t as the underlying type for all
enumerated controls. This makes users of ControlValue more complex. To
simplify them, specialize the control_type template for enum types, to
support construction of ControlValue directly without a cast.

Support for DNG capture is conditioned by the availability of libtiff,
which is indicated by the HAVE_TIFF macro set by meson. The dng_writer.h
header then defines HAVE_DNG, which is used in a couple of places to
conditionally compile DNG-related code. Most of the other locations
where conditional compilation is required use HAVE_TIFF.
Using both HAVE_TIFF and HAVE_DNG is confusing. HAVE_DNG would be a
better name, but as the macro is defined in dng_writer.h, it would
require all files that need to test for DNG support to include that
header. Failure to include it (directly or indirectly) would result in
the code covered by the macro to be silently disabled.
To avoid the confusion, standardize on using HAVE_TIFF everywhere and
drop HAVE_DNG.

It is possible that the maximum sensor size (returned by
CameraSensor::resolution()) is not supported by the pipeline. In such
cases, a filter function is required to filter out resolutions of the
camera sensor, which cannot be supported by the pipeline.
Introduce the filter function filterSensorResolution() in RkISP1Path
class and use it for validate() and generateConfiguration(). The
maximum sensor resolution is picked from that filtered set of
resolutions instead of CameraSensor::resolution().

Which is not only what many other pipeline handlers use, but also a good
lower limit when dealing with DRM and similar APIs. Even Mesas EGL and
Vulkan WSI implementations use for the reason outlined in mesa commit
992a2dbba80aba35efe83202e1013bd6143f0dba:
> When the compositor is directly scanning out from the application's buffer it
> may end up holding on to three buffers. These are the one that is is currently
> scanning out from, one that has been given to DRM as the next buffer to flip
> to, and one that has been attached and will be given to DRM as soon as the
> previous flip completes. When we attach a fourth buffer to the compositor it
> should replace that third buffer so we should get a release event immediately
> after that. This patch therefore also changes the number of buffer slots to 4
> so that we can accomodate that situation.
Given the popularity of this buffer number the bump should be unlikely
to cause problems. At the same time it may help with performance or
even work around glitches.
The previous number was introduced in commit
a8964c28c80fb520ee3c7b10143371081d41405a without mentioning a specific
reason against the change at hand.

The black level is likely to get updated, if ever, only after exposure
or gain changes. Don't compute its possible updates if exposure and
gain are unchanged.
It's probably not worth trying to implement something more

Use the standard libcamera mechanism to report the "current" controls
rather than delaying updates by counting from the last update.
A problem is that with software ISP we cannot be sure about the sensor
delay. The original implementation simply skips exposure updates for 2
frames, which should be enough in most cases. After this change, we
assume the delay being exactly 2 frames, which may or may not be correct
and may work with outdated values if the delay is shorter.
According to Kieran, the wrong parts are also wrong on the
IPU3/RKISP1/Mali pipelines and only RPi have this correct. We need to
fix this, by correctly specifying the gains in the libipa camera sensor
helpers. The sooner the better because this change could introduce a
risk of increasing oscillations.
This patch also prepares moving exposure+gain to an algorithm module
where the original delay mechanism would be a (possibly unnecessary)
complication.

It's more natural to represent color gains as floating point numbers
rather than using a particular pixel-related representation.
double is used rather than float because it's a more common floating
point type in libcamera algorithms. Otherwise there is no obvious
reason to select one over the other here.
The constructed color tables still use integer representation for
efficiency.
Black level still uses pixel (integer) values, for consistency with
other libcamera parts.

After black level handling has been moved to an algorithm module, white
balance and the construction of color tables can be moved to algorithm
modules too.
This time, the moved code is split between stats processing and
parameter construction methods. It is also split to two algorithm
modules:
- White balance computation.
- Gamma table computation and color lookup tables construction. While
this applies the color gains computed by the white balance algorithm,
it is not directly related to white balance. And we may want to
modify the color lookup tables in future according to other parameters
than just gamma and white balance gains.
Gamma table computation and color lookup tables construction could be
split to separate algorithms too. But there is no big need for that now
so they are kept together for simplicity.
This is the only part of the software ISP algorithms that sets the
parameters so emitting setIspParams can be moved to prepare() method.
A more natural representation of the gains (and black level) would be
floating point numbers. This is not done here in order to minimize
changes in code movements. It will be addressed in a followup patch.

The black level determination, already present as a separate class, can
be moved to the prepared Algorithm processing structure. It is the
first of the current software ISP algorithms that is called in the stats
processing sequence, which means it is also the first one that should be
moved to the new structure. Stats processing starts with calling
Algorithm-based processing so the call order of the algorithms is
retained.
Movement of this algorithm is relatively straightforward because all it
does is processing stats.
The comment about getting black level from the tuning files is dropped.
The black level will be taken from CameraSensorHelper if available and
that will be implemented in one of the followup patches.
Black level is now recomputed on each stats processing. In a future
patch, after DelayedControls are used, this will be changed to recompute
the black level only after exposure/gain changes.
The black level depends on the sensor used, the computed value can be
reused in a followup capture sessions with the same sensor. Thus it is
sufficient to (re)set the initial value in BlackLevel::init.

This patch adds frame and bufferId arguments to stats related calls.
Although the parameters are currently unused, because frame ids are not
tracked and used and the stats buffer is passed around directly rather
than being referred by its id, they bring the internal APIs closer to
their counterparts in hardware pipelines.
It serves as a preparation for followup patches that will introduce:
- Frame number tracking in order to switch to DelayedControls
(software ISP TODO #11 + #12).
- A ring buffer for stats in order to improve passing the stats
(software ISP TODO #2).
Frame and buffer ids are unrelated for the given purposes but since they
are passed together at the same places, the change is implemented as a
single patch rather than two, basically the same, patches.

Software ISP image processing algorithms are currently defined in a
simplified way, different from other libcamera pipelines. This is not
good for several reasons:
- It makes the software ISP code harder to understand due to its
different structuring.
- Adding more algorithms may make the code harder to understand
generally.
- Mass libcamera code changes may not be easily applicable to software
ISP.
- Algorithm sharing with other pipelines is not easily possible.
This patch introduces basic software ISP IPA skeletons structured
similarly to the other pipelines. The newly added files are currently
not used or compiled and the general skeleton structures don't contain
anything particular. It is just a preparation step for a larger
refactoring and the code will be actually used and extended as needed in
followup patches.

Add to ControlId information about the names and values of enum, in the
event that the ControlId is an enum type. This allows applications to
query the ControlId for the names of the enum values, so that they can
be displayed on a UI, for example. Without this, it was necessary to use
macros of NameOfControlNameValueMap, which is difficult to use and is
very inflexible.
There already exists a map from name -> value in generated code. Reuse
this and pass it to the ControlId constructor, which in turn generates
the reverse map. The reverse map is then exposed to applications.

Now, that the generic interpolator is available, use it to do the
interpolation of the lens shading tables. This makes the algorithm
easier to read and remove some duplicate code.

The MatrixInterpolator is great for interpolation of matrices for
different color temperatures. It has however one limitation - it can
only handle matrices. For LSC it would be great to interpolate the LSC
tables (or even polynomials) using the same approach. Add a generic
Interpolator class based on the existing MatrixInterpolator. This class
can be adapted to any other type using partial template specialization.

When accessing a nonexistent key on a dict the YamlObject returns an
empty element. This element can happily be cast to a string which is
unexpected. For example the following statement:
yamlDict["nonexistent"].get<string>("default")
is expected to return "default" but actually returns "". Fix this by
introducing an empty type to distinguish between an empty YamlObject and
a YamlObject of type value containing an empty string. For completeness
add an isEmpty() function and an explicit cast to bool to be able to
test for that type.
Extend the tests accordingly.

Using `DMA_BUF_IOCTL_SYNC` is required for DMABUFs in order to ensure
correct output. Not doing so currently results in occasional tearing
and/or backlashes in GL/VK clients that use the buffers directly for
rendering.
An alternative approach to have the sync code in `MappedFrameBuffer` was
considered but rejected for now, in order to allow clients more
flexibility.
While the new helper is added to an annoymous namespace, add
timeDiff to the same namespace and remove the static definition as a
drive by.

Various parts of libcamera print the representation of a MediaLink by
inline joining the parts to make a string representation.
This repeated use case can be supported with a common helper to print
the MediaLink in a common manner using the existing toString() and
operator<< overload style to make it easier to report on MediaLink
types.
This implementation will report in the following style:
'imx283 1-001a'[0] -> 'video-mux'[0]
