gst: libcamerasrc: Implement selection and acquisition
This adds code to select and acquire a camera. With this, it is now possible to run a pipeline like: gst-launch-1.0 libcamerasrc ! fakesink Though no buffer will be streamed yet. In this function, we implement the change_state() virtual method to trigger actions on specific state transitions. Note that we also return GST_STATE_CHANGE_NO_PREROLL in GST_STATE_CHANGE_READY_TO_PAUSED and GST_STATE_CHANGE_PLAYING_TO_PAUSED transitions as this is required for all live sources.
