This is the last big change necessary to create the `constellation_traits` crate. This moves the data structure for messages that originate from the `ScriptThread` and are sent to the `Contellation` to `constellation_traits`, effectively splitting `script_traits` in half. Before, `script_traits` was responsible for exposing the API of both the `ScriptThread` and the `Constellation` to the rest of Servo. - Data structures that are used by `ScriptToConstellationMsg` are moved to `constellation_traits`. The dependency graph looks a bit like this: `script_layout_interface` depends on `script_traits` depends on `constellation_traits` depends on `embedder_traits`. - Data structures that are used in the embedding layer (`UntrustedNodeAddress`, `CompositorHitTestResult`, `TouchEventResult` and `AnimationState`) are moved to embedder_traits, to avoid a dependency cycle between `webrender_traits` and `constellation_traits`. - Types dealing with MessagePorts and serialization are moved to `constellation_traits::message_port`. Testing: This is covered by existing tests as it just moves types around. Signed-off-by: Martin Robinson <mrobinson@igalia.com> Signed-off-by: Martin Robinson <mrobinson@igalia.com>
