1393. [port] Bind to individual IPv6 interfaces if IPV6_IPV6ONLY
is not available in the kernel to prevent accidently
listening on IPv4 interfaces.

1371 [bug] notify-source-v6, transfer-source-v6 and
query-source-v6 with explict addresses and using the
same ports as named was listening on could interfere
with nameds ability to answer queries sent to those
addresses.
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.
from the named.conf "listen-on" statement, sockets
were still listening on the removed addresses due
to reference count loops. [RT #325]
Now there is one client manager object per interface instead of a single
global one; when an interface goes away, it simply destroys the associated
client manager, which will cause all its clients to be shut down in an
orderly fashion.
both a 'listen-on' and a 'listen-on-v6' ACL. We are still waiting for
the 'listen-on-v6' config file option to set the latter explicitly,
but at least the default value now tracks the 'port' option and the
'-p' command line option.
Mostly, several functions that take pointers as arguments, almost
always char * pointers, had those pointers qualified with "const".
Those that returned pointers to previously const-qualified arguments
had their return values qualified as const. Some structure members
were qualified as const to retain that attribute from the variables
from which they were assigned.
Minor other ISC style cleanups.
dns_dispatch_create() no longer exists. dns_dispatch_createtcp()
and dns_dispatch_getudp() are the replacements. _createtcp() takes
a bound, connected TCP socket, while _getudp() will search for
a sharable UDP socket, and if found, attach to it and return a
pointer to it. If one is not found, it will create a udp socket,
bind it to a supplied local address, and create a new dispatcher
around it.
dns_dispatch_remove{request,response}() no longer take the dispatch
as an argument.
query-source can now be set per view.
The dispatch manager holds onto three memory pools, one for
allocating dispatchers from, one for events, and one for
requests/replies. The free list on these pools is hard-coded,
but set to 1024. This keeps us from having to dig into the
isc_mem_t the pools draw from as often.
dns_resolver_create() and dns_view_createresolver() require that
valid dispatchers be passed in; dispatchers are no longer created
for the caller.
