bridge: Allow setting multicast_router option
The multicast_router option of a bridge allows to control the forwarding
behaviour of multicast packets independant of the listener state:
* 0: Only forward if specific listener is present
* 1 (default): Forward if specific listener or a multicast router
was detected (currently only learned via query messages, no MRD
support yet)
* 2: Always forward any multicast traffic on this port
Since MRD is not mandated you might end up with silent multicast routers
(e.g. if your link has more than one multicast router; only one can
become the selected, "noisy" querier). Here you might need a manual
configuration option like the "multicast_router" option.
Other scenarios where this can be useful are for instance:
* Segmentation of IGMP/MLD domains together with ebtables
* Dedicated bridge port for monitoring/debugging purposes

bridge: Allow setting multicast_to_unicast option
With this patch the multicast_to_unicast feature can be disabled for all

whether to enable or disable ap-isolation, for instance.

bridge: Fix multicast_to_unicast feature by hairpin+isolate
All IGMP and MLD versions suffer from a specific limitation (from a
snooping switch perspective): Report suppression.
Once a listener hears an IGMPv2/3 or MLDv1 report for the same group
itself participates in then it might (if this listener is an IGMPv3 or
MLDv2 listener) or will (if this is an IGMPv1/2 or MLDv1 listener)
refrain from sending its own report.
Therefore we might currently miss such surpressing listeners as they
won't receive the multicast packet with the mangled, unicasted
destination.
Fixing this by first isolating the STAs and giving the bridge more
control over traffic forwarding. E.g. refraining to forward listener
reports to other STAs.
For broadcast and unicast traffic to an STA on the same AP, the hairpin
feature of the bridge will reflect such traffic back to the AP
interface. However, if the AP interface is actually configured to
isolate STAs, then hairpin is kept disabled.

proto-shell: add checkup timeout to restart interface.
This is mainly for protocols with no_proto_task set. L2TP with xl2tpd
is such a case and the issue this commit tries to address is that xl2tpd
could fail redialing the connection (segfault or abort) without the
notice of netifd causing the concerned interface being left down.
This patch solves it by allowing users to configure an timeout value
instructing netifd to check if the interface is in up state after its
last attempt to setup it and try again if that is not the case.

netifd v2: Fix source routing for IPv4
According to the OpenWRT Network documentation for route, the 'source' option is
"The preferred source address when sending to destinations covered by the
target". However, netifd currently stores this value in RTA_SRC on
NEWROUTE/DELROUTE.
RTA_SRC is not used by kernel when handling NEWROUTE nor DELROUTE for IPv4
routes. When adding a new IPv4 route, the source is stored in RTA_PREFSRC and
the option works as specified in documentation. For IPv6, the address is still
stored in RTA_SRC as to not break source-destination routing for IPv6.
v2: Limit patch to IPv4, to prevent breaking IPv6 configurations (thanks Steven
Barth)

netifd: Read current link state when processing netlink event
Netifd commit
b2dcb02570939d98b92c7c55db1c328693a5d52a introduces
a race condition resulting into infinite toggling interfaces
(eg static interfaces with linksensing enabled, vlan interfaces
with proto none (#18106)) when linksensing is enabled resulting into
a crash.
As netlink event messages will be queued on the netlink event socket
the included lower up interface flag will not always represent the
current link state when netifd processes the netlink messages;
by reading the current link state when a netlink event message is
parsed the correct info is passed to the device layer.
This will avoid continuous interface toggling (down/up) triggered
by link state changes based on outdated netlink interface info.

proto-shell: fix for not handling switch from DHCP to static race
When a shell script call is finished, proto_shell_task_finish( ) is
called to monitor processes, and determine the next interface state.
When the interface is brought up after a reconfiguration from dhcp
to static, it will first try to (erroneously?) reconfigure the
interface for DHCP. Upon doing this, it realises the mistake and
kills off the script by setting the state to S_SETUP_ABORT. This is
done by the proto_shell_handler. When this happens. the scripts
have 1 second to finish.
When this happens, S_SETUP_ABORT in proto_shell_task_finish( )
should issue a 'teardown' event to the shell script to deconfigure
the interface. It is here that things go wrong.
Shell scripts do not execute commands themselves, they should
finish as quick as possible. This is very race condition sensitive,
though; Instead of executing commands, they post messages to
execute commands. It is therefore possible that when the script
finishes, there's still commands to execute.
The dhcp protocol handler script, one of the scripts involved,
notifies netifd of changes by (indirectly) calling
proto_shell_update_link( ).
Once every so often, the dhcp script will not be finished in time,
and proto_shell_task_finish( ) cannot immediately continue,
because (in this case) the proto_task is still pending.
If this happens, the proto_shell_task_finish( ) will wait, but if
the proto_shell_update_link( ) notification is then received, it
will set the statemachine to idle, thus breaking the
S_SETUP_ABORT. Furthermore, an event is generated to indicate that
the network interface should be set to UP, rather than DOWN.
This confuses netifd, and the result is a stuck process that does
not respond to UCI calls anymore.
Note that a similar situation happens in the S_TEARDOWN state in
proto_shell_task_finish( ).
The fix, although a bit ugly, is to prevent the UP event from
being sent, and not to reset the state machine to idle in
proto_shell_update_link( ).
