If more then one interface get up/down at once mwan3 could be in a
undefined state, because more then one mwan3 hotplug script are running
and editing the iptables.
Lock the critical section should solve this issue.

If mwan3track will not stop immediately after sending the kill signal,
the clean_up handler will delete the pid file later while the new mwan3track is
already running.
This could result in a situation that mwan3track is running
more then once because the old mwan3track service could not be killed,
because the pid file is missing.
Using pgrep to kill all mwan3track for the tracked interface and not using
pid file should fix this issue.

If interface is getting down by netifd (unplug ethernet cable)
mwan3track will not recognize this change. It will also generate an
additional down event when he notice does his tracking interface is offline.
Mwan3track will now be informed by a signal (trap) USR1 during down event
that the interface is already down. An additional down event will not be
generated.

If mwan3track detects a failure the interval check will change to
"failure_interval" value until this interface is declared "offline".
After interface gets "offline" normal "interval" value is used again.
If interface ping is successful again "recovery_interval" value is used until
interface is declared "online" again.
Using the different intervals will accelerate the wan line detections on
failure and recovery.

On interfaces with interface proto "qmi|ncm" and option dhcp
enabled the interface will be changed to $iface_4 | $iface_6. The
interface mapping in mwan3 will not recognize this interface. To fix
this issue an ubus call will check if an upper interface exists.
