The main highlight is the move to calloop to handle all the requests
which makes it possible to remove all the active polling and clean the
data reading/writing, as well as accepting arbitrary long payloads.
This update also fixes the CI for the repository by moving it to github
actions, sets the minimum rust version, and edition to 2021.
Fixes#46.
Fixes#44.
Fixes#34.
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.
* Multiple seat support and api refractor
* Remove the need for two GlobalManagers
* Remove unnecessary `Arc<Mutex<_>>` and `if let`s with `unwrap()`
* Use cloned display to create eventloop in `new_threaded()`
* Update docs
* Wrap display to event queue
