tm: support for changing dst_uri in branch routes

- dst_uri can now be changed in branch routes, if the branch
  route is not called during dns failover (which never happens,
  but might be enabled in the future).
- dst_uri can now be checked in branch routes. The
  dst_uri on branch route entry will be the branch next hop
  (initial next hop and not the dns resolved one) if a
  t_relay() based on uri was used, or empty if a destination was
  forced (e.g. t_relay_to_udp(127.0.0.1, 9)).
- s/print_uac_request/prepare_uac_request to better reflect what
  is actually doing
- prepare_uac_request() will now perform the DNS lookups and directly
  update the branch dst inside the transaction.
- add_uac() must now be called with a special flag during DNS
  failover (UAC_DNS_FAILOVER).
