Test that the IPC supports sending data and file descriptors over the
IPC medium. To be able to execute the test two parts are needed, one
to drive the test and act as the libcamera (master) and a one to act as
the IPA (slave).
The master drives the testing posting requests to the slave to process
and sometimes respond to. A few different tests are performed.
- Master sends an array to the slave which responds with a reversed copy
of the array. The master verifies that a reversed array is returned.
- Master tries to send an empty message making sure that the send call
fails.
- Master sends a list of file descriptors and ask the slave to calculate
and respond with the sum of the size of the files. The master verifies
that the calculated size is correct.
- Master sends a pre-computed size and a list of file descriptors and
asks the slave to verify that the pre-computed size matches the sum of
the size of the file descriptors.
- Master sends two file descriptors and asks the slave to join the file
contents in a new file and respond with its file descriptor. The
master then verifies that the content of the returned file descriptor
matches the order of the original two files.

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.

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<>.

To prepare for specialising the CameraConfiguration class in pipeline
handlers, return a pointer to a camera configuration instead of a
reference from Camera::generateConfiguration(). The camera configuration
always needs to be allocated from the pipeline handler, and its
ownership is passed to the application.
For symmetry, change Camera::configure() to take a CameraConfiguration
pointer instead of a reference. This aligns with our coding practice of
passing parameters that are modified by the callee by pointer.

Refactor the CameraConfiguration structure to not rely on Stream
instances. This is a step towards making the camera configuration object
more powerful with configuration validation using "try" semantics.
The CameraConfiguration now exposes a simple vector-like API to access
the contained stream configurations. Both operator[]() and at() are
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().

Instead of requesting the default configuration for a set of streams
where the application has to figure out which streams provided by the
camera is best suited for its intended usage, have the library figure
this out by using stream usages.
The application asks the library for a list of streams and a suggested
default configuration for them by supplying a list of stream usages.
Once the list is retrieved the application can fine-tune the returned
configuration and then try to apply it to the camera.
Currently no pipeline handler is prepared to handle stream usages but
nor did it make use of the list of Stream IDs which was the previous
interface. The main reason for this is that all cameras currently only
provide one stream each. This will still be the case but the API will be
prepared to expand both pipeline handlers and applications to support
streams usages.
