This is a fix for the the following change:
3d824ea288
Before the change, it was only possible to execute a shell script. To
remove this restriction, a binary or other script language can now also
be used for 'mwan3.user'. Unfortunately, the old shell script was not
executable for older mwan3 version. During a sysupgrade with config transfer,
this 'mwan3.user' script could not be executed for newer mwan3 versions.
To fix this, the calling script checks whether the 'mwan3.user' is executable,
and if not, this executable bit is now set.

To allow the script to define what it should be run with.
This let's the user use bash if it's available, or python, or perl, etc.

Replace locks on /var/run/mwan3.lock with locks via procd.
This fixes a deadlock issue where mwan3 stop would have a procd
lock, but a hotplug script would have the /var/run/mwan3.lock
Locking can be removed from mwan3rtmon since:
1) procd will have sent the KILL signal to the process during
shutdown, so it will not add routes to already removed interfaces on
mwan3 shutdown and
2) mwan3rtmon checks if an interface is active based on the
mwan3_iface_in_<IFACE> entry in iptables, and the hotplug script
always adds this before creating the route table and removes it
before deleting the route table
Fixes github issue #13704
(https://github.com/openwrt/packages/issues/13704)
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.
version bump to 2.9.0

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

User scripts conversion from luci-app-wan3 will be simplified if the variables
