The class allows to get the list of available cameras on the system as well as getting some static information about them such as their unique ID, display name, physical position and sensor orientation. This makes QCamera::availableDevices() and QCamera::deviceDescription() obsolete. This patch contains the API, documentation and auto-tests but not the actual implementation by each backend (except for retrieving the default camera device). [ChangeLog][QtMultimedia] Added new QCameraInfo class [ChangeLog][QtMultimedia] QCamera: availableDevices() and deviceDescription() are deprecated, use QCameraInfo instead Change-Id: I64fd65729ab26a789468979ed5444ee90bb82cd0 Reviewed-by: Christian Stromme <christian.stromme@digia.com>
