Subject: Various fixups for nomenclature - see full commit message

* USE_AUTOCONF->USE_SLAAC to be more consistent with IPv6 terminology
* PREFIX6->PREFIXLEN to be more consistent with IPv6 terminology

Thanks to David Spencer (idlemoor) for the patch to the above

* AUTOCONF_TIMEOUT->SLAAC_TIMEOUT to be consistent with USE_SLAAC change

Since some options for IPv6 no longer end in '6', we can relax the naming
of others, so these make sense: IPADDR6->IP6ADDR ; IPALIASES6->IP6ALIASES

Update to rc.inet1.conf example file - thanks to David Spencer.
