Revert "Adding a restriction for legal RID values."
This reverts commit 07f3279a730980583403b78c3762c5d246d1d9be.
Reason for revert: Suspect of producing consistent failure in some Chrome trybots, blocking rolls.
Failed test:
external/wpt/webrtc/RTCPeerConnection-addTransceiver.https.html
First failure:
https://ci.chromium.org/p/chromium/builders/try/linux-rel/64597
Original change's description:
> Adding a restriction for legal RID values.
>
> According to the spec, RID values should be constrained to only
> alpha-numeric values. This was not enforced in our implementation to
> allow for more flexibility.
> It has been brought to our attention that some values that we currently
> consider legal (such as the '~', '=' ';' characters) might cause confusion
> with the simulcast syntax that uses these characters to indicate other
> meanings.
> What's worse, is that some characters, when used in RIDs (such as
> \u{1f937} \u{1f4a9} and \u{1f926}) cause uncontrollable laughter for some
> users which might also be a health hazard.
> This change resolves these issues by restricting RIDs to alpha-numeric.
