2019-05-23libcamera: camera: Return a pointer from generateConfiguration()Laurent Pinchart
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.

2019-05-23libcamera: Use stream roles directly instead of StreamUsageLaurent Pinchart
In order to prepare for an API overhall of the camera configuration generation, remove the StreamUsage class and replace its uses by stream roles. The size hints can't be specified anymore, and will be replaced with an API on the StreamConfiguration to negotiate configuration parameters with cameras.

2019-05-23libcamera: camera: Rename configureStreams() and streamConfiguration()Laurent Pinchart
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.

2019-04-05libcamera: camera: Add support for stream usagesNiklas Söderlund
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.

2019-03-14test: camera: Add state machine testNiklas Söderlund
Add a test of the different access level enforced by the state machine inside the camera. The state machine aims to limit operations on the camera to the cameras state. The test exercises all states of the camera and verifies that only the intended operations are possible at each stage.
