For some purposes (e.g. SNAT, vxlan) it might be necessary to have an
additional address just for the router which is not attached to any
interfaces. Addresses like this are typically added to the loopback
interface.
The new options "router_ip" and "router_ip6" are added to the gateway
config to allow the user to configure such addresses. It is possible to
both specify the address with or without a subnet size.
The default configuration contains the IPv4 loopback address
(127.0.0.1/8) explicitly, but this is not necessary. These addresses are
configured automatically, even if they are not present in the
configuration, so they can safely be removed, if present.
The filters of our routing daemon babeld are adjusted accordingly, so
the newly added addresses are announced correctly.

The IPv4 source routing features was removed from babeld with version
1.10. Therefore, the first_table_number option is not needed anymore and
its existance stops babeld from starting up.
As babeld 1.10 is included with OpenWrt 21.02, which is currently used
for our firmware, this option is removed.
