674c2bf1f1 gstreamer: Pass Stream to RequestWrap::addBuffer()
For symmetry with RequestWrap::removeBuffer(), pass the Stream pointer
to addBuffer(). This handles streams at the GstPad level instead of the
GstBuffer level, which allows making the GstLibcameraPool API a bit
cleaner by removing the gst_libcamera_buffer_get_stream() helper
function.

d1934c6490 ipa: libipa: algorithm: Add an algorithm registration mechanism
In order to allow dynamic instantiation of algorithms based on tuning
data files, add a mechanism to register algorithms with the IPA module.
The implementation relies on an AlgorithmFactory class and a
registration macro, similar to the pipeline handler registration
mechanism. The main difference is that the algorithm registration and
instantiation are implemented in the Module class instead of the
AlgorithmFactory class, making the factory an internal implementation
detail.

83df785493 ipa: libipa: Introduce a Module class template
libipa defines an abstract Algorithm class template that is specialized
by IPA modules. IPA modules then instantiate and manage algorithms
internally, without help from libipa. With ongoing work on tuning data
support for the RkISP1, and future similar work for the IPU3, more code
duplication for algorithms management is expected.

To address this and share code between multiple IPA modules, introduce a
new Module class template that will define and manage top-level concepts
for the IPA module.

The Module class template needs to be specialized with the same types as
the Algorithm class. To avoid manual specialization of both classes,
store the types in the Module class, and replace the template arguments
of the Algorithm class with a single Module argument from which the
other types are retrieved.

ac955c425d pipeline: ipa: raspberrypi: Correctly report available control limits
The ipa currently advertises a static ControlInfoMap to specify the available
controls and their limits. Fix this limitation by having the IPA populate a new
ControlInfoMap with updated limits for ExposureTime, AnalogueGain, and
FrameDurationLimits controls based on the current sensor mode. This new
ControlInfoMap is then returned back to the pipeline handler and available to
the application after a successful Camera::configure() call.

Before the first call to Camera::configure(), this ControlInfoMap provides some
reasonable default limits for ExposureTime, AnalogueGain, and
FrameDurationLimits. However, applications must not rely on these values, but
obtain the correct limits after the call to Camera::configure().

53ada24e63 pipeline: ipa: raspberrypi: Move ControlInfoMap to the IPA
Currently the pipeline handler advertises controls handled by the IPA from a
static ControlInfoMap defined in the raspberrypi.h header. This change removes
this header file, and instead the IPA returns the ControlInfoMap to the pipeline
handler from the ipa::init() function. This is done to allow the IPA to adjust
the limits of the controls based on the sensor mode in a subsequent change.

7ec3bfedbe meson: options: Disable pycamera by default
The libcamera Python bindings is still experimental and it relies on some
features in pybind11 that are not yet upstreamed, so a special branch has
to be downloaded as a subproject.

This conflicts with the build process used by most Linux distributions,
since there is expected that all the dependencies will be fulfilled by
-devel packages present in the build root.

To allow libcamera to be built by distros, let's disable the pycamera by
default. This can still be enabled with `meson build -Dpycamera=enabled`.

f44ce70d9b Documentation: Fix createRequest unique_ptr
camera->createRequest() function return std::unique_ptr<Request>, then
manipulate Request as std::unique_ptr.
This solve the following error, during compilation:

error: cannot convert ‘std::unique_ptr<libcamera::Request>’ to ‘libcamera::Request*’ in initialization

71bdc1e441 libcamera: pipeline: simple: Support scaling on the sensor
As the simple pipeline handler targets simple pipelines on the SoC side,
it often gets used with platforms that have a YUV sensor capable of
outputting different sizes. Extend the heuristics used for pipeline
discovery and configuration to scale as much as possible on the sensor
side, in order to minimize the required bandwidth.

5fe1f00f19 libcamera: pipeline: simple: Store sensor resolution in configuration
When enumerating the supported configurations, store the corresponding
sensor resolution in the SimpleCameraData::Configuration structure and
use it when configuring the camera, instead of hardcoding the sensor
full resolution. This prepares for support of downscaling in the camera
sensor.

6984f07c0e libcamera: pipeline: simple: Factor out format test to separate function
To prepare for the implementation of a more complex format discovery
method, factor out code that tries a pipeline configuration to a
separate function. No functional change intended.
