After CONNECT, the EIS implementation needs to add one or more seats. The libei client can only create devices within those seats. This mirrors the wayland hierarchy as well as the X.Org one. The seat has a set of allowed capabilities, so the client knows ahead of time when it may not be possible to create a specific device. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>
