Patch by Thiago de Barros Lacerda <thiago.lacerda@openbossa.org> on 2013-11-08
Reviewed by Eric Carlson.

Source/WebCore:

If invalid parameters are passed on RTCPeerConnection creation we must throw a TypeError exception.
According to the spec it requires a Dictionary argument, the RTCConfiguration, which is mandatory.

Please notice that this patch does not make every tests run as expected,
RTCPeerConnectionHandlerMock needs to be update to deal with contraints.

Existing tests were updated.
