netifd: Add sendredirects config support
Setting /proc/sys/net/ipv4/conf/*/send_redirects is useful if a single
layer-2 domain is shared among routed subnets.
Sending redirects will prevents traffic from taking unnessesary detours
through a gateway in cases where direct connectivity on layer 2 exists.
This is commonly the case if an existing LAN infratructure with dump
switches is used to additionally carry routing protocols like OLSR
which are supported only by some nodes on the network.
It's important to note that the default value for send_redirects
differs for interface types (it's enabled on physical ethernet
interfaces, but disabled e.g. on VLANs) due to olsrd changing
/proc/sys/net/ipv4/conf/default/send_redirects during boot, thus the
default differs also depending e.g. on the way an on-board switch is
integrated on specific boards (as eth0 exists before olsrd is started,
eth0.1 gets created by netifd later on...)
Having a way to explicitely enable or disable send_redirects is
thus desireable also to unify the default behaviour among different,
but seemingly similar devices supported.

bridge: make learning and unicast-flood configurable per bridge port
Tuning these two options allows a more fine grained configuration of the
forwarding database (fdb) of a bridge.
The former allows to enable or disable the learning of the presence of
MAC addresses behind a bridge port. (default: enabled on all ports)
The latter allows to tune the behaviour in case a destination MAC address
of a frame is unknown to the fdb, like only flooding on specific ports or
not flooding on any port. (default: flood on all ports, except incoming)
This can be useful to create a dumb hub, for instance for monitoring
purposes. Or in larger layer 2 mesh networks to avoid keeping redundant
databases (e.g. with the batman-adv translation table).

alias : Fix interface aliased on top of a static interface not getting active
An interfaces referring to a static interface is not getting active when doing a network
reload or ifup.
The problem is triggered by alias_set_device which is not clearing the pending update
(mostly a null device due to the previous down event) when the same device is set as the
current device via alias_notify_device.
As a result alias_set_device_state when called will overwrite the device with an invalid
pending device meaning the interface will not be set available anymore and thus will
stay down.

Revert "add prelocal table to manipulate locally destinated traffic"
Revert commit
3eea8576d48d9b20cc1c6b46f54c7345a39d13aa since it changes the
default behaviour of user ip rules in unexpected ways.
When an ip rule is added without an explicit priority then the kernel will
use the priority value of the 2nd rule, decreased by one.
On an ordinary system, the 2nd rule usually is "from all lookup main" with
priority 32766 which means that user rules are added beginning with priority
32765 in decreasing order.
Since the introduction of the prelocal rule at prio 0 and the subsequent
moving of "from all lookup local" to prio 1, the kernel will insert all user
rules with priority 0, between the prelocal and local lookup rules, leading
to broken routing in many common scenarios.

bridge: multicast: Export some parameters RFCs suggest to be tunable
RFCs suggest some parameters of IGMP and MLD to be configurable by
the administrator. With this patch the following parameters are
configurable:
* robustness (default: 2)
* query_interval (default: 12500 [125s])
* query_response_interval (default: 1000 [10s])
* last_member_interval (default: 100 [1s])
Depending on the size and nature of the network topology administrators
might want to increase or decrease these parameters.
netifd will take care of configuring any other parameters which are
dependant on the ones above and set them according to the formulas
provided in the RFCs. These parameters of the bridge are
membership_interval, querier_interval, startup_query_interval,
startup_query_count and last_member_count.
RFCs allow setting three more parameters to be configurable:
startup_query_interval, startup_query_count and last_member_count.
However this patch does not export them, as they can be indirectly
tuned via the given, exported four parameters, too.

netifd: Do not add local/source policy rules multiple times
interface_ip_set_enabled() is usually called two times right after one another,
once to handle config_ip and once to handle proto_ip. As long as
ip->iface->l3_dev.dev is set, the local/source policy rules are updated.
This value is in several cases set on both config_ip and proto_ip, causing the
rules to be added multiple time. The reason is that the kernel does not respect
the NLM_F_* flag for rules. In other words, the rule state has to be managed by
the routing daemon.
Since the local/source policy rules are bound to iface, this commit solves the
problem by adding a flag to interface which stores the current rule state. The
flag follows the enabled-paramter passed to interface_ip_set_enabled(), similar
to route-> and addr->enabled. The flag breaks the alignment of the interface
struct, but based on earlier commits this seems to be ok.
I have tested the patch in different configurations and have not found any
regression.
