[lwip-users] dns: remember multiple IP addresses patch

[Jan Menzel]

Hi all!
        I'd like to share a small patch with you that allows the dns subsystem
to remember and handle more then one IP address from response messages.
It basically parses out all IP address and stores them in an array. It
then returns a random entry. The patch was created against lwip 2.0.0RC2
and requires LWIP_RAND(). I hope it might be as useful for others as it
was for us.
