IPv6 support

As of this release, Open Server on IBM AIX platforms supports IPv6.

Below is an interfaces file entry where the last two server addresses are in IPv6 numeric format:

BARNARD_OS
   master tcp ether barnards.sybase.com 18200
   query tcp ether barnards.sybase.com 18200
   master tcp ether barnards.v6.sybase.com 18200
   query tcp ether barnards.v6.sybase.com 18200
   master tcp ether
     fd77:55d:59d9:165:203:baff:fe68:aa12 18200
   query tcp ether
     fd77:55d:59d9:165:203:baff:fe68:aa12 18200

NoteAll master and query lines in the interfaces file must begin with a tab.
