pgrep is pretty slow as it needs to read all /proc/*/cmdline
or /proc/*/status, and it's called twice per wan.
Add STARTED and PID files to speedup mwan3_get_mwan3track_status().

Set the score value to the maximum value when the connected function is
called. The same happens with a disconnected event, the score value is
there set to zero.

Refactoring the score handling, so that only one action could take place
during run. The behaviour should be more comprehensible, since several
score actions are not processed at the same time.

Up to now on every interface down event a mwan3 disconnected event was
send. This is wrong because if the interface was never connected, then a
disconnected event should not get generated. This commit fixes this bug.

If the interface goes into failure state (is disconnecting)
then with this change one hotplug.d event is generated.
The same is true for the recovery state (is connecting), when the interface
comes back from a failure state.
In both cases, a hotplug.d event for the iface is triggered. Once
with the $ACTION=disconnecting and once for the $ACTION=connecting.

By default, ping does a reverse DNS of the IP that you are pinging.
When you have a network issue (such as when a link has just gone down
and you haven't yet marked it down), this lookup can cause failures on
tests for links that are still good.
This option only works for iputils ping.
For busybox the option is not evaluated, but it is accepted without
throwing an error.

version tag, rather than iputils date tag
This commit sends a test ping to localhost to evaluate the

Use "mwan3 use" to wrap a command with interface bindings so that you can
avoid the mwan3 rules and test behavior on a specific interface.
eg "mwan3 use wan ping -c1 1.1.1.1"
Additional binding arguments to the command will have their system
calls intercepted and ignored.
eg "mwan3 use wan ping -c1 -I tun0 1.1.1.1" will use the
device associated with "wan", rather than "tun0".

Rather than using a special mwan3 user to manage mwan3track's tracking
packets, this commit implements a small helper library to bind to
device and to set a fwmark so that the tracking packets can be routed
out of the correct interface.
This provides a consistent method for binding to a device rather than
relying on various packages potentially buggy implementations. For
example: #8139 and #12836
This helper issue also allows for more tracking methods to be added
even if they do not have a command line option to bind to device,
such as iperf3 (eg #13050).

start all mwan3mon and mwan3track instances on mwan3 start
if an interface is down when mwan3track starts, it waits
for a signal from the hotplug script to start
procd can then handle stopping all of the scripts when mwan3
is halted

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.

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.

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.
