Added autogen.sh script that rebuilds using autotools and runs configure

Modified configure.in to include some debug build option info at the end
of the scripts execution. Can be removed by release time.
Modified configure.in to include a --with-ipv6 option
Default build is without IPv6 support now to enable you need to use the
--with-ipv6 command line option to configure.
Modified plugins/utils.* to use USE_IPV6
