For a long time, `gfx_traits` has held a lot of things unrelated to graphics and also unrelated to the `gfx` crate (which is mostly about fonts). This is a cleanup which does a few things: 1. Move non `gfx` crate things out of `gfx_traits`. This is important in order to prevent dependency cycles with a different integration between layout, script, and fonts. 2. Rename the `msg` crate to `base`. It didn't really contain anything to do with messages and instead mostly holds ids, which are used across many different crates in Servo. This new crate will hold the *rare* data types that are widely used. Details: - All BackgroundHangMonitor-related things from base to a new `background_hang_monitor_api` crate. - Moved `TraversalDirection` to `script_traits` - Moved `Epoch`-related things from `gfx_traits` to `base`. - Moved `PrintTree` to base. This should be widely useful in Servo. - Moved `WebrenderApi` from `base` to `webrender_traits` and renamed it to `WebRenderFontApi`.
