This commit entirely reworks the internal structure of the entire crate, as well as some of its APIs. This crate only accepts a C pointer to a Wayland display object, since the target audience of this crate are libraries without a wayland-client types. Also since seat information is not presented in such clients most of the time, the clipboard entirely relies on its seat tracking.
