Summary: nat traversal and b2bua

Initial Comment:
The changes put in nat_traversal.c did not quite stop opensips from crashing when the module is loaded and the b2bua is used.  I think a return statement is probably also needed.  This incompatibility should probably be mentioned in the b2bua and nat_traversal docs.  I don't think it's unreasonable for a person to believe that top hiding would be a good fit with natted clients.

Message:
Hi Richard,

Indeed, a "return" was missing -I took care of it. 

Actually the incompatibility is not between b2bua and NAT, but between
b2bua and nat_traversal, as nat_traversal is using dialog support in order
to do nat traversal. If you use other nat modules (like nathelper), you
should not have this issue.

Thanks and regards,
Bogdan
