This is largely to aid compatibility with other non-volatile stores
that have limited sized names but support a name space. This might
open a path to more compact storage of the key names although that is
not implemented here.
* When IPv6 is enabled the http server and the captive portal dns now also
accept IPv6 connections. The interface and peer IPv6 address are now also
reported.
* The http server no longer redirects <name>.local to an IP address for better
integration with mDNS.
* Add mDNS support, for the extras/mdnsresponder or the LWIP mDNS responder,
and enable the LWIP mDNS responder for examples/wificfg.
