The message.h and mutex.h headers are not used in the libcamera public API. Make them private to avoid there usage in applications, and to prevent having to maintain them with a stable ABI. As mutex.h is used by libcamerasrc, the GStreamer element must switch from the libcamera_public to the libcamera_private dependency.
