[WebRTC] Validating RTCConfiguration according to the spec

[Thiago de Barros Lacerda]

Spec states that:
   - iceServers should not be an empty list
   - the entry in the configuration dictionary is "urls", instead of "url"
   - urls can be either a list or a string
Fixing all that in RTCConfiguration validation when creating a RTCPeerConnection

Nit: this can move down where the variables are used.
