    dns: update unbound_resolve(), resolve nexthop using the HOST's address family
    
    For nexthop, instead of trying IPv4 and then IPv6 and taking the first
    that succeeds, resolve nexthop's DNS name using the previously
    determined HOST's address family.
    
    For sourceip, there's no change.  However I suspect it should be doing
    something similar but with the previously determined CLIENT's address
    family.
    
    More specifically, in unbound_resolve():
    
    - drop redundent srclen parameter (always use strlen)
    - replace AF_* af with ip_info *afi
    - directly convert raw A/AAAA record to an address
    
    in callers:
    
    - update parameter list
    - for NEXTHOP, per above, pass HOSTFAM into dns lookup function
    - for SOURCEIP, no change, try IPv4 then IPv6
    - when #ifdef unbound, first try with ttoaddress_num()
    - when #ifndef unbound, use ttoaddress_dns()
    
    (which leads to deleting tnatoaddr())
