[libnice] example for TURN??

[Jack Wang]

I found someone had a similar experience with me :D

http://markmail.org/message/w7x6bgnnpjc6hmsj#query:+page:1+mid:647krhvnth3eqqgt+state:results


As he did - I comment the line which returns  STUN_VALIDATION_UNAUTHORIZED,
finally, I got the relay candidate now!

But I'm stiil confused with this,
I'll keep tracking and figuring out it.
