Great work, thank you so much. A few things I'd like cleaned up before its time to merge.
I'll try to take some time this evening to more thoroughly review and test out this PR.

Lets drop the for here - we're only closing one data channel at a time.
Alternatively, if the sctp_stream_reset_event can actually hold multiple streams to reset, lets loop across all of them.

The event could hold multiple streams as it's a list. I would ideally want to loop across each of them, but I'm not sure how to do that without knowing the size.

I'd like to hide the specifics of resetting streams inside the DataChannel - the PeerConnection here is meant to be a somewhat close mirror of the Javascript DataChannel API, which doesn't expose SCTP directly.

I agree! I shouldn't expose this. Will fix soon.

Fixed in 91db2d4. Let me know if this is okay.

Also fixes the function prototype.
This is computed from strreset_length field from sctp_stream_reset_event struct. This field is the total length in bytes of the delivered event, including the header. https://tools.ietf.org/html/rfc6525#section-6.1.1
* Heap allocation of struct and free it soon after * Simplified 'len'
