The site.node_client_prefix6() is only used internally by the l3roamd
protocol. Therefore it is unnecessary to expose it to an administrator.
Instead, if node_client_prefix6 is unspecified in the site, generate an
IPv6 Unique Local Address prefix from the site domain_seed.
This updates the site documentation as well and marks this setting as
both optional and deprecated.
Note: If you had the node_client_prefix6 specified before and want to
use the new autogeneration from the domain_seed instead then this will
break compatibility and will need a gluon-scheduled-domain switch.

log-file /dev/stderr is broken for babeld as it eats log messages for debug log.
This commit gets rid of the option. This allows -d N to be used as babeld command
line option.
