2d7ca109c5 1442. [func] New fuctions for manipulating port lists: 
dns_portlist_create(), dns_portlist_add(),
                        dns_portlist_remove(), dns_portlist_match(),
                        dns_portlist_attach() and dns_portlist_detach().

1441.   [func]          It is now possible to tell dig to bind to a specific
                        source port.

1440.   [func]          It is now possible to tell named to avoid using
                        certian source ports (avoid-v4-udp-ports,
                        avoid-v6-udp-ports).

27e6e3708d 1147. [func] Set IPV6_V6ONLY on IPv6 sockets if supported by 
the OS.  listen-on-v6 { any; }; should no longer
                        result in IPv4 queries be accepted.  Similarly
                        control { inet :: ... }; should no longer result
                        in IPv4 connections being accepted.  This can be
                        overridden at compile time by defining
                        ISC_ALLOW_MAPPED=1.

135b1206c9 don't retry UDP receives after they return an error - 
an error return from the socket library means the library has already
decided that the error is not retryable and likely to throw
us into an infinite loop if retried

054777a694 eliminated redundant assignments to disp->shutting_down; 
if shutting down due to error, set disp->shutdown_why to the appropriate result
code, not to ISC_R_EOF

Andreas Gustafsson
8ed67113ec there is no need for each dispatch to have a separate reference to 
the blackhole list; they can use the blackhole list of the dispatch
manager directly. This eliminates some unsafe unlocked accesses to
the reference count of the blackhole list dns_acl_t object

35f06ab0e6 Clients now listen on sockets instead of accepting queries from dispatchers. 
When a socket is shared by clients and query-source, the client hands off
responses to the dispatcher.

by the first call to dns_dispatch_getudp(), subsecquent calls can raise

public.

Tidy dispatch_allocate().

entropy and mctx are now gone from dns_qid_t.
