This makes mwan3rtmon check if mwan3_get_routes returns a route
before removing it. This helps with IPv6 routes with source address
selector removal where multiple original routes are transformed to
the same mwan3 route if one of the source routes is removed while
the others are kept.

Addition of routes to mwan3_connected ipset is broken. The ipset name was
changed from mwan3_connected_v4/6 to mwan3_connected_ipv4/6, but this
change was not reflected in mwan3rtmon.

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)
- support trailing route space from iproute2
- add routes even when iface is down
- fix source_routing argument check
- add quotes in logging to better detect issues with trailing spaces

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

handle creation of routing tables in mwan3rtmon to avoid race
conditions and potentially missing routes
handle ipv6 routes that have expiry
update directly connected ipset when routes are added or deleted
add fall through rules so that the default routing table is not
used if no rule in the interface-specific routing table matches
add option to comply with mwan3 source based routing
get default route parameters from main routing table

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

use only committed uci changes for updating routing table
use functions.sh functions rather than uci command line tool
to find interfaces for routing table.
consolidate rtmon_ipv4 and rtmon_ipv6 functions into a single function

This bug was introduced since dd206b7d0b
mwan3_remon_ipv4 and mwan3_remon_ipv6 is command to run not a variable
I add some comments on them hopefully people will notice it
