dnsmasq: bump to dnsmasq v2.77test3
New test release (since test1) includes 2 LEDE patches that are upstream and may be dropped, along with many spelling fixes. Add forthcoming 2017 root zone trust anchor to trust-anchors.conf. Backport 2 patches that just missed test3: Reduce logspam of those domains handled locally 'local addresses only' Implement RFC-6842 (Client-ids in DHCP replies) Compile & run tested Archer C7 v2 Signed-off-by: Kevin Darbyshire-Bryant <kevin@darbyshire-bryant.me.uk>

+Subject: [PATCH] Decrease the number of individual sites listed in log.
+
+By default 30 first servers are listed individually to system log, and
+then a count of the remaining items. With e.g. a NXDOMAIN based adblock
+service, dnsmasq lists 30 unnecessary ad sites every time when dnsmasq
+evaluates the list. But the actual nameservers in use are evaluated last
+and are not displayed as they get included in the "remaining items" total.
+
+Handle the "local addresses only" separately and list only a few of them.
+Remove the "local addresses only" from the general count.

-
-Treat Servfail as a recoverable error instead of a hard error.
-
-A misconfigured dns forwarder upstream can return a Servfail faster than
-a correctly configured one.
-
-In the case of a dnssec misbehaving, it will misbehave on all correctly
-configured upstreams. In the case of a normal DNS query, the original
-behavior of dnsmasq here was more robust.
