Victor Boivie a04b8b5043 dcsctp: Handle losing first DATA on ordered stream
When a FORWARD-TSN is received as the first chunk on an ordered stream,
it will fail to set the new "next expected SSN" that is present in the
FORWARD-TSN as that stream hasn't been allocated yet. It's allocated
when the first DATA is received on that stream.

This is a non-issue for ordinary data channels as the first message on
any stream will be the "Data Channel Establishment Protocol" messages,
which are always sent reliably. But if prenegotiated channels are used,
and the very first packet received on an ordered data channel is lost
_and_ signaled to the receiver as lost _before_ the receiver has
received any other fragments on that data channel, future messages will
not be delivered on that channel.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development
