Patch to add CAA dissecting to DNS, version 2.

Hi,

thanks for your comments. I incorporated most of your feedback. However, what's
the benefit of replacing 

+      proto_tree_add_text(caa_tree, tvb, cur_offset, 1, "Tag length: %d",
tag_len);
+      proto_tree_add_text(caa_tree, tvb, cur_offset + 1, tag_len, "Tag: %s",
tag);
+      proto_tree_add_text(caa_tree, tvb, cur_offset + 1 + tag_len, value_len, 

by proto_tree_add_item? The values are already added as items before and can be
searched for in wireshark. Additionally, then some more hf-fields for tag
length and tag would be needed. These fields are partially redundant as there
are already fields for the different tags.

Furthermore I would like to add a searchable "dns.caa" field so that people can
look for DNS CAA traffic. How do I do this without adding anything to the
protocol tree?
