Do not randomize resolving of IP addresses in getaddr()
Based on a discussion on the mailing list and in the IRC meeting Feb 18, it was decided to remove get_random() from the getaddr() function as that can conflict with round-robin/randomization done by DNS servers. This change must be documented in the release notes. Signed-off-by: David Sommerseth <dazo@users.sourceforge.net>
