split /www into subdirs for several services; adapt uhttpd config

This patch splits the single uhttpd instance into two uhttpd instances
with www root /www/<servicename> for the following purposes:
- service :: self-service / debugging / status.xml
- redirection :: use for splash/robinson redirection

The uhttpd uci config is adapted: by default all instances declared
there are disabled; They shall be enabled by the FSM inetable. To this
end a listen_http directive will be added and the config type will be
changed from 'disabled' to 'uhttpd' by state transition scripts.
