play: Introducing the new playback library

This aims to be a replacement for the GstPlayer library. In GstPlay, notifications are
sent as application messages through a dedicated GstBus. The GMainContext-based
signal dispatcher was replaced by a GObject signal adapter, now relying on the
bus to emit its signals. The signal dispatcher is now optional and fully
decoupled from the GstPlay object.
