Hello, Wouter!

As i said earlier i have made patches set for Unbound-1.11.0 to log over DNSTAP both addresses - source (from client) address and destination (local or service) one. My core idea is to introduce NSD-like structure called unbound_socket and use it in comm_points of netevent code. So please look in my patches, i hope they will be reasonable and secure for application.
And only one TODO that i have to do in future - right now i can log only the front side, i.e. client requests and responses. Upstream side is currently logged as 0.0.0.0 local address. Its a question of some rework of outside_network code.

All the patches are in attached tarball.

Thank you in advance!
