Adds --with-lwres and --enable-emulate-getaddrinfo but are not used in any of

the code at this time. Has a check for IPv6 support but only runs if using the
emulate-getaddrinfo routines, this needs to be modified.
!!! I need input from results of this run on various platforms to see what
results are seen in plugins/config.h so please help test !!!
