AnimationValue::mGecko and AnimationValue::mServo are mutually
exclusive, so we have to make sure mGecko.IsNull() returns reasonable
value, or we will got assertions. Hence, we should initialize it during
constructing StyleAnimationValue from Servo side.

rewrites the whole websocket infrastructure to properly follow the Fetch
spec and to make switching to a different websocket library easier.
stylo: Bug 1336769 - Make Angle constructors return a finite value.
It is possible to input an extra large angle, e.g. rotate(9.5e+307rad), so we need to clamp it to avoid any assertion in Gecko.
