The IPsec ip route table has the default number 220.
If mwan3 has more then 7 bits set (124 interfaces) then if mwan3 down is
executed the table is also cleared. To solve this set default max 7
bits in the mmx_mask for mwan3.

Adjust the dependency from ip-full back to ip.
Returning back to "ip" is now possible as busybox does not provide
"ip" any more, making "ip" again reference to ip-tiny or ip-full.

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.

If the date is changed by ntp the age value of mwan3 on ubus could jitter.
Use instead the uptime value from /proc/uptime which will not change during

Interfaces of some PtP protocols do not have a real gateway. In that
case ubus may fill them with '0.0.0.0' or even leave it blank. This
will cause error when adding new routing rule.

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.

Use common function to toggle ip address in /var/state/mwan3.
Change also to use toggle function and not set function. If ip address
is often changed every change is saved to /var/state/mwan3.

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 globals config section with option local_source.
With this config option the self interface generation will be done now
automatically on hotplug event. You can specify which interface (ip)
sould be used for router traffic. To replace the self intereface in the
config set local_source to "lan".
The default option is none, so it will not change default behavior if a
"self" interface is configured in the network section.

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.

Even though error was fixed the interface checks still fails, if last_resort

To fix this issue do not remove failure interface from iptables change on

Adds support for interface tracking using either ping, arping or
httping. This allows to track interface status on networks with filtered
ICMP traffic or simply to monitor data link layer etc.
To facilitate binding to a specified interface its IP address is passed
as a new mwan3track parameter. It's currently required by httping
and possibly by other tools that may be added in the future.
