This bug was introduced since dd206b7d0b
mwan3_remon_ipv4 and mwan3_remon_ipv6 is command to run not a variable
I add some comments on them hopefully people will notice it

Before this change two disconnected events were generated. This is wrong!
The disconnected event is impliciet generated by the hotplug script on ifdown
event. The mwan3track script is notified by a USR1 signal which
generates the disconnectd event. The additional "disconnectd" event on
ifdown is not required.

Add to ubus the missing output information "policies" which could already
be observed with the command "mwan3 status".

If we set the option "local_source" in the globals mwan3 section to "none",
traffic generated by the router it self will always use the default route from
the wan interface with the lowest metric. If this interface is down
the router traffic still uses the connection with the lowest metric but
this is disconnected. Load balancing and failover from the lan site is
still possible. Only router generated traffic is not load balanced and
could not use failover.
To solve this issue with router initiated traffic add the additional
option "online_metric" to the mwan3 interface section.
If the interface is connected then this lower "online metric" is set in the
default routing table.
With this change we have at least a failover with router initiated
traffic.

Get downtime information for the tracked mwan3 wan interfaces.
The information shows how long this interface is in disconnected state.

If a interface is down, call ubus will return an null message which is
used to json_load, it causes json_get_vars gets value from last load and
l3_device various is nonzero.

1. Test link quality based on packet loss & latency w.r.t. pre-defined high and low watermark values.
2. Extended ubus support to provide packet loss & latency information per wan per track_ip

We need always three of the firewall mask value for
* default routing table
* blackhole
* unreachable
the other will be used for the interfaces.
* If we have set the mmx_mask to max 0xFF00 (8 bit set) we could use max 252
interfaces.
* If we have set the mmx_mask to min 0x0E00 (3 bit set) we could use max 4
interfaces.
Only the ones are counting from the firewall mask value.
Minimal three firewall mask bit vaules must be set.
Maximal eight firewall mask bit vaules could be set.
Table overview mmx_mask value bits vs. max interfaces
mmx_mask value bits set 1 -> not usefull
mmx_mask value bits set 2 -> not usefull
mmx_mask value bits set 3 -> 4 Interfaces (mask example 0x0E)
mmx_mask value bits set 4 -> 12 Interfaces
mmx_mask value bits set 5 -> 28 Interfaces
mmx_mask value bits set 6 -> 60 Interfaces
mmx_mask value bits set 7 -> 124 Interfaces
mmx_mask value bits set 8 -> 252 Interfaces (mask example 0xFF)

Add a new ACTIONs:
* connected ACTION is called once if mwan3track reach all configured track_ips
* disconnected ACTION is called once if mwan3track is unable to reach the track_ips
The connected/disconnected will called only by mwan3track in opposite
the ACTIONs ifup/ifdown will also be called by netifd.

In some situation it is not enough to send a SIGTERM to mwan3track to
ask service to stop accurate. If this does not work send him a SIGKILL
to prevent mwan3track running more then once per interface.

This commit fixed what 6d99b602 was supposed to fix without affecting
interface-bound traffic.
Before 6d99b602 interface-bound traffic was working normally as long
as at least one interface was online. However when the last interface
went offline, it was impossible to ping and such state was
unrecoverable.
Commit 6d99b602 fixed unrecoverable offline state problem (it was
possible to ping -I iface) but messed inteface-bound traffic. Traffic
with interface source address was not working if the interface was in
"offline" state, even if another interface was online.
The problem was caused by an inconsistent "offline" interface state:
iptables-related rules were kept while routing table and policy were
deleted.
The idea behind this commit is to:
1. Keep all the rules for each interface (iptables, routing table,
policy) regardless of its state. This ensures consistency,
2. Make interface state hotplug events affect only iptables'
mwan3_policy_* rules. Interface-related iptables, routing table
and policy is removed only when mwan3 is manually stopped.
To make such changes possible, it's necessary to change the way
mwan3_policy_* rule generator keeps track of interface state hotplug
events.
Until now, it checked for the existence of custom interface-related
routing table (table id 1, 2, 3, ...). Clearly we can no longer rely
on that so each interface state is stored explicitly in file.

Fixes the following bugs introduced in commit 815e83d4:
- hotplug: invalid parameter order when initial interface state is "online",
mwan3track expects initial state to be the third argument
- hotplug: missing source ip address when initial interface state is "offline"
- mwan3track: source ip address should be the fourth argument

Add new interface config option "inital_state".
If interface comeing up the first time(mwan3 start, boot),
there are now two option for interface behaviour:
- online (default as is now)
Set up interface regardless wether tracking ip are reachable or not.
- offline
Set up interface first to ping tracking ip and if they are reachable set up
the interface completely.
