54489ba167 Improve locking performance in dispatch.c 
3316.	[tuning]	Improved locking performance when recursing.
			[RT #28836]

   - Use one lock per memory pool instead of associating
     them all with a single 'pool_lock' in the dispatch manager.
   - Reduce the critical sections for qid->lock in get_dispsocket(),
     deref_portentry() and dns_dispatch_addresponse2().
   - Added a memory pool for socket events in dns_dispatch_t.
   - Add an isc_socketevent_t member in the resquery_t object, and use
     it with isc_socket_sendto2() instead of using isc_socket_sendto()
   - Tuned the memory pools in dispatch.c for better performance

000a8970f8 3011. [func] Change the default query timeout from 30 seconds 
to 10.  Allow setting this in named.conf using the new
                        'resolver-query-timeout' option, which specifies a max
                        time in seconds.  0 means 'default' and anything longer
                        than 30 will be silently set to 30. [RT #22852]
