81afca4078 pipeline: rpi: Introduce CameraData::CropParams
In preparation for assigning separate crop windows for each stream, add
a new CropParams structure that stores the existing ispCrop_ and
ispMinCropSize_ as fields. Use a new std::map to store a CropParams
structure where the map key is the index of the stream configuration in
the CameraConfiguration vector.

At preset, only a single CropParams structure will be set at key == 0 to
preserve the existing crop handling logic.

fb23268105 pipeline: rpi: Remove CameraData::scalerCrop_
Do not cache the scalerCrop_ parameter. The cached value is used to
update the request metadata, but since this is not an expensive
operation (and can only occur once per frame), caching it is of limited
value.

This will simplify logic in a future commit where we can specify a
crop per-output stream.

12b553d691 libcamera: rkisp1: Plumb the dw100 dewarper as V4L2M2M converter
Plumb the dw100 dewarper as a V4L2M2M converter in the rkisp1 pipeline
handler. If the dewarper is found, it is instantiated and buffers are
exported from it, instead of RkISP1Path. Internal buffers are allocated
for the RkISP1Path in case where dewarper is going to be used.

The RKISP1 pipeline handler now supports scaler crop control through
the converter. Register the ScalerCrop control for the cameras created
in the RKISP1 pipeline handler.

485f92ac06 libcamera: rkisp1: Prepare for additional camera controls
Currently the rkisp1 pipeline handler only registers controls that are
related to the IPA. This patch prepares the rkisp1 pipeline-handler to
register camera controls which are not related to the IPA.

Hence, introduce an additional ControlInfoMap for IPA controls. These
controls will be merged together with the controls in the pipeline
handler (introduced subsequently) as part of updateControls() and
together will be registered during the registration of the camera.
This is similar to what IPU3 pipeline handler handles its controls.

1b0b90a332 libcamera: converter: Add interface to support cropping capability
If the converter has cropping capability on its input, the interface
should support it by providing appropriate virtual functions. Provide
Feature::InputCrop in Feature enumeration for the same.

Provide virtual setInputCrop() and inputCropBounds() interfaces so that
the converter can implement its own cropping functionality.

The V4L2M2MConverter implements these interfaces of the Converter
interface. Not all V4L2M2M converters will have cropping ability
on its input, hence it needs to be discovered at construction time.
If the capability to crop is identified successfully, the cropping
bounds are determined during configure() time.

7cbd05dc01 libcamera: software_isp: Black level from tuning file
This patch allows obtaining a black level from a tuning file in addition
to the camera sensor helper.  If both of them define a black level, the
one from the tuning file takes precedence.

The use cases are:

- A user wants to use a different black level, for whatever reason.

- There is a sensor without known gains but with a known black level.
  Because a camera sensor helper cannot be defined without specifying
  gains, the only way to specify the black level is using the tuning
  file.  Software ISP uses its fallback gain handling in such a case.

e879a86979 libcamera: yaml_parser: Take string keys in std::string_view
In many cases a static string literal is used as key. Thus
having the argument type be `const std::string&` is suboptimal
since an `std::string` object needs to be constructed before
the call.

C++17 introduced `std::string_view`, using which the call
can be done with less overhead, as the `std::string_view`
is non-owning and may be passed in registers entirely.

So make `YamlObject::{contains,operator[]}` take the string keys
in `std::string_view`s.

Unfortunately, that is not sufficient yet, because `std::map::find()`
takes an reference to `const key_type`, which would be `const std::string&`
in the case of `YamlParser`. However, with a transparent comparator
such as `std::less<>` `std::map::find()` is able to accept any
object as the argument, and it forwards it to the comparator.

So make `YamlParser::dictionary_` use `std::less<>` as the comparator
to enable the use of `std::map::find()` with any type of argument.

2f621920ea libcamera: geometry: Clarify Rectangle's top-left corner
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.
