fixup for duplication of NSECs / NSEC3s after following CNAMEs

(esp. wildcard CNAMEs and in-zone CNAMEs that then include nodata or nxdomain proofs) where the CNAME is followed again to include more NSECs. git-svn-id: file:///svn/unbound/trunk@787 be551aaa-1e26-0410-a405-d3ace91eadb9

+28 November 2007: Wouter
+	- Changeup plan for 0.8 - no complication needed, a simple solution
+	  has been chosen for authoritative features.
+	- you can use single quotes in the config file, so it is possible
+	  to specify TXT records in local data.
+	- fixup small memory problem in implicit transparent zone creation.
+	- test for implicit zone creation and multiple RR RRsets local data.
+	- local-zone nodefault test.
+	- show testbound testlist on commit.
+	- iterator normalizer changes CNAME chains ending in NXDOMAIN where
+	  the packet got rcode NXDOMAIN into rcode NOERROR. (since the initial
+	  domain exists).
+	- nicer verbosity: 0 and 1 levels.
+	- lower nonRDquery chance of eliciting wrongly typed validation
+	  requiring message from the cache.
+	- fix for nonRDquery validation typing; nodata is detected when
+	  SOA record in auth section (all validation-requiring nodata messages
+	  have a SOA record in authority, so this is OK for the validator),
+	  and NS record is needed to be a referral.
+	- duplicate checking when adding NSECs for a CNAME, and test.
+
+27 November 2007: Wouter
+	- per suggestion in rfc2308, replaced default max-ttl value with 1 day.
+	- set size of msgparse lookup table to 32, from 1024, so that its size
+	  is below the 2048 regional large size threshold, and does not cause
+	  a call to malloc when a message is parsed.
+	- update of memstats tool to print number of allocation calls.
+	  This is what is taking time (not space) and indicates the avg size
+	  of the allocations as well. region_alloc stat is removed.
+
+22 November 2007: Wouter
+	- noted EDNS in-the-middle dropping trouble as a TODO.
+	  At this point theoretical, no user trouble has been reported.
+	- added all default AS112 zones.
+	- answers from local zone content.
+		* positive answer, the rrset in question
+		* nodata answer (exist, but not that type).
+		* nxdomain answer (domain does not exist).
+		* empty-nonterminal answer.
+		* But not: wildcard, nsec, referral, rrsig, cname/dname,
+			or additional section processing, NS put in auth.
+	- test for correct working of static and transparent and couple
+	  of important defaults (localhost, as112, reverses). 
+	  Also checks deny and refuse settings.
+	- fixup implicit zone generation and AA bit for NXDOMAIN on localdata.
+
+21 November 2007: Wouter
+	- local zone internal data setup.
+
+20 November 2007: Wouter
+	- 0.8 - str2list config support for double string config options.
+	- local-zone and local-data options, config storage and documentation.
