avahi: Add patch to fix Win10 mDNS issues
Windows 10 will respond to mDNS messages when it really shouldn't, resulting in a lot of logging. Pulling the change from avahi upstream. This will be fixed in avahi 0.6.32 External References: https://bugs.launchpad.net/ubuntu/+source/avahi/+bug/1342400 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=794145 https://bugzilla.redhat.com/show_bug.cgi?id=1240711 https://social.technet.microsoft.com/Forums/en-US/b334e797-ef80-4525-b74a-b4830420a14e/windows-10-spams-network-with-invalid-mdns-response-packets?forum=win10itpronetworking Signed-off-by: Brad Mouring <brad.mouring@ni.com> Signed-off-by: Ross Burton <ross.burton@intel.com>

+Subject: [PATCH] Don't log warnings about invalid packets (Fixes
+ lathiat/avahi#10)
+
+Various invalid packets would generate a warning, in particular
+Windows 10 generates response packets with no answer records and
+generally seemingly empty. Unsure why at this stage.
+
+This results in spamming syslog quite a lot on busy networks,
+similar issues like this have occured over time due to changes
+in various operating systems and specs (e.g. Avahi #284, #282)
+
+Rather than just disable this single message or case, I have
+pre-emptively turned the majority of these bad packet messages
+into debug messages. They can still be output on production
+builds if reuqired using the --debug option (no rebuild required).

+
+Pulled from git://github.com/lathiat/avahi de7cde87, which
+is slated for avahi 0.6.32.
