[ortc] RTCDtlsTransportState due to common Close Alert.

ibc has just created a new issue for https://github.com/openpeer/ortc:

== RTCDtlsTransportState due to common Close Alert. ==
Let's have an already established/connected DTLS connection (state = 
`connected`). The remote peer closes its side so sends a signaling 
"BYE" and also a DTLS Close Alert. Usually the DTLS Close Alert 
arrives before to us.

In this scenario (a common Close Alert rather than an "error"), what 
would be our `RTCDtlsTransportState` upon receipt of such a Close 
Alert? According to the spec it would become `failed`:


>closed 
>The DTLS connection has been closed intentionally via a call to 
stop(). Calling transport.stop() will also result in a transition to 
the "closed" state.

>failed 
>The DTLS connection has been closed as the result of an error (such 
as a DTLS alert or a failure to validate the remote fingerprint).

But that would trigger a `RTCDtlsTransportStateChangedEvent` and the 
app would be notified about a DTLS "failure" and would act according 
(for example by displaying a warning message to the user or whatever),
 but after a few milliseconds the signaling "BYE" will arrive, 
invalidating such a warning.

So, would not make sense that, in this scenario in which we receive a 
DTLS Close Alert within a correctly connected DTLS transport, our 
`RTCDtlsTransportState` becomes `closed` instead of `failed`?
