improve startup and runtime performance by
1) moving common startup procedures out of hotplug script when called
from mwan3 start
2) reducing calls to iptables to check status of rules
3) consolidating iptables updates and updating with iptables-restore
4) do not wait for kill if nothing was killed
5) running interface hotplug scripts in parallel
6) eliminate operations in hotplug script that check status on every
single interface unnecessarily
7) consolidate how mwan3track makes hotplug calls
8) do not restart mwan3track on connected events
This is a significant refactor, but should not result in any breaking
changes or require users to update their configurations.

to find interfaces for routing table.

Fix shellcheck SC2230

Once applied to everything concerning OpenWrt we can disable the busybox
feature `which` and save 3.8kB.

This adjustment of the locks fixes the race condition when a mwan3
hotplug script and a mwan3 command are running at the same time.

Due to a missing config load function call, mwan3 start runs ifup for an empty
list of interfaces, thus not calling ifup at all.
This commit introduces the missing config_load call.

An interface can have both a /64 and a /128 from a provider.
In such a case, use the address from the /64 to do the ping check, not
the /128.

Pinging IPv6 hosts using an interface as a source specifier seems
troublesome. See https://bugs.openwrt.org/index.php?do=details&task_id=2897
for more detail.
Use the desired source interface's IP address instead.

Till now we could only ping http targets on port 80. With this change by
adding the config boolean config option httping_ssl we could also ping
https ping targets on port 443.

Sometimes the return value of `ubus -S call network.interface.wan status`
cause `json_load` to return `Failed to parse message data` error.
To avoid this, the JSON data always should be quoted with double quotes.

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.

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.

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.
