53cf671865 1445. [bug] DNS_ADBFIND_STARTATROOT broke stub zones. This has 
been replaced with DNS_ADBFIND_STARTATZONE which
                        causes the search to start using the closest zone.

1444.   [func]          dns_view_findzonecut2() allows you to specify if the
                        cache should be searched for zonecuts.

ca50fa0230 Partial fix for RT #2053. The potential for deadlock still exists, 
but it is much less likely to occur because we now only take the ADB lock when the
external reference count reaches zero, not every time it is decremented.
Althought this does not actually fix the bug, it at least lets us make
progress on testing fixes for other bugs affecting shutdown of multithreaded
servers.

d1cc210d20 RT #927 fix from Bob: 
759.   [bug]           The resolver didn't turn off "avoid fetches" mode
                        when restarting, possibly causing resolution
                        to fail when it should not.  This bug only affected
                        platforms which support both IPv4 and IPv6. [RT #927]

 758.   [bug]           The "avoid fetches" code did not treat negative
                        cache entries correctly, causing fetches that would
                        be useful to be avoided.  This bug only affected
                        platforms which support both IPv4 and IPv6. [RT #927]

7b5172166d Waking up once a second to clean one bucket is excessive. Change the 
default values (and dependencies) so that the clenup routine is called once
ever 30 seconds and cleans 8-9 buckets.
