The new processing applies only in Unified Plan mode.
Plan B retains the old-style processing.
This is a reland of 1fa06041bc
Original change's description:
> Make negotiationneeded processing in PeerConnection spec compliant.
>
> This CL fixes the problem of misfired negotiationneeded notifications due
> to the lack of a NegotiationNeeded slot and the proper procedure to
> update it.
