Daniel Mack 3db468ea87 network: add support for setting MDB entries 
Multicast snooping enabled bridges maintain a database for multicast
port memberships to decide which mulicast packet is supposed to
egress on which port.

This patch teaches networkd to add entries to this database manually
by adding `[BridgeMDB]` sections to `.network` configuration files.

Yu Watanabe 659ad3a0af network: do not make link in configured state when no address is assigned 
When DHCP6 and RA are enabled, and RA does not provide any addresses,
then link may become configured state even if no address is assigned,
due to the time-lag between RA completion and DHCP reply.
This makes if DHCP is explicitly enabled, then link must have at least
one valid address to be in the configured state.

Yu Watanabe 290696e512 Revert "network: Don't send RA with zero router lifetime when restarting radv" 
This reverts commit d469cea3bd.

Michael Marley d469cea3bd network: Don't send RA with zero router lifetime when restarting radv 
While investigating https://github.com/systemd/systemd/issues/16356, I
discovered that networkd stops the radv service before adding or updating
prefixes and then starts it again.  This causes networkd to send an RA with
a router lifetime of zero, causing the routes to flap on systems receiving
the RA for a fraction of a second before radv is started again and proper
RAs are sent.  That has the potential to cause issues with latency-sensitive
traffic like gaming or VoIP.  This patch adds a boolean argument to the
sd_radv_stop() function to control this behavior.  The zero lifetime RA is
still sent whenever radv is actually being stopped, but when it is being
restarted for a prefix update (from networkd-dhcp6.c), the final RA is no
longer sent to avoid the route flapping.
