1cf709b1d2 libcamera: formats: Add ImageFormats
Add a new class to hold format information for V4L2 devices and
subdevices. The object describes the relationship between either pixel
formats (V4L2 devices) or media bus codes (V4L2 subdevice) and a list of
image sizes which can be produced with that format.

d9a468aaac test: camera: Increase runtime for capture test
Upstream commit 2978a505aaa981b2 ("media: vimc: stream: fix thread state
before sleep") changes the frame rate when capturing from the vimc raw
capture video nodes. The commit changes the frame rate from thousands of
frames per second to to roughly fifty.

The libcamera capture test was written with the assumption that vimc
would keep providing this fast frame rate and ran for a very short time
to decrease the overall run time of tests. This is no longer possible
and the test fails as it can't capture enough frames in its runtime,
increase the runtime to match the new vimc frame rate.

2b1a908b52 libcamera: camera: Add a validation API to the CameraConfiguration class
The CameraConfiguration class implements a simple storage of
StreamConfiguration with internal validation limited to verifying that
the stream configurations are not empty. Extend this mechanism by
implementing a smart validate() method backed by pipeline handlers.

This new mechanism changes the semantic of the camera configuration. The
Camera::generateConfiguration() operation still generates a default
configuration based on roles, but now also supports generating empty
configurations to be filled by applications. Applications can inspect
the configuration, optionally modify it, and validate it. The validation
implements "try" semantics and adjusts invalid configurations instead of
rejecting them completely. Applications then decide whether to accept
the modified configuration, or try again with a different set of
parameters. Once the configuration is valid, it is passed to
Camera::configure(), and pipeline handlers are guaranteed that the
configuration they receive is valid.

A reference to the Camera may need to be stored in the
CameraConfiguration derived classes in order to access it from their
validate() implementation. This must be stored as a std::shared_ptr<> as
the CameraConfiguration instances belong to applications. In order to
make this possible, make the Camera class inherit from
std::shared_from_this<>.

passing parameters that are modified by the callee by pointer.

The CameraConfiguration now exposes a simple vector-like API to access

provided to access elements. The isEmpty() method is renamed to empty()
and the methods reordered to match the std::vector class.

As applications need access to the Stream instances associated with the
configuration entries in order to associate buffers with streams when
creating requests, expose the stream selected by the pipeline handler
through a new StreamConfiguration::stream().

2ca2d65870 libcamera: camera: Rename configureStreams() and streamConfiguration()
Rename the configureStreams() and streamConfiguration() methods to
configure() and generateConfiguration() respectively in order to clarify
the API. Both methods deal with CameraConfiguration objects, and are
thus not limited to streams, even if a CameraConfiguration currently
contains streams only.

While at it, remove the qcam MainWindow::configureStreams() method that
is declared but never defined or used.

c1bbbd3b5b libcamera: ipa_module: add IPA shared library module
Implement a class to wrap around an IPA module shared object.

For now, just load a struct IPAModuleInfo with symbol name
ipaModuleInfo from an IPA module .so shared object.

Also provide a public header file including the struct IPAModuleInfo,
structured such that both C and C++ IPA modules are supported.
