Allow configuration of TCP timeout while waiting for response 
This allows us to configure how long Unbound will wait for a response
on a TCP connection.

Allow configuration of persistent TCP connections 
Added 2 new options to configure previously hardcoded
values: max-reuse-tcp-queries and tcp-reuse-timeout. These
allow fine-grained control over how unbound uses persistent
TCP connections to authority servers.
