mDNS is supposed to be case-insensitive (like DNS). Both advertising and
discovery logic should use case-insensitive matching instead of
case-sensitive matching.
The case sensitive matching can be found by grepping the String.equals()
and Arrays.equals() check across the whole code base. Each occurrence is
analyzed carefully to list up all necessary fixes.
