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

Allow `mwan3 interfaces` to get uptime via an internal function and
thus remove the dependency on rpcd for `mwan3 interface` calls.

It was somewhat opaque how the variable a is questioned. To show this
better the variable is now a string and not a boolean. So you can see
directly what should happen. With a boolean you always have to think
about what it means when 0 or 1 is used.

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)
when the network procd service restarts, it flushes the ip rules. We
need to add these rules back. Since hotplug events are triggered when
the networks come back online, adding this call to the hotplug script
is the most convenient place to refresh the rules.

he line is too long. For the future it is better to split it into
several lines and make it more clearly arranged. In case of a future
change, not the whole line will be marked as a change.

When the interface section was changed, the changed configuration
options were not applied.
This commit adds the service reload handling again.

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).
