Adjust the +CPIN? cmd so it works for huawei 3G sticks too

On its own, ntpd does not sync fast enough at bootup, so bring back the ntpdate sync but improve it so it can't get stuck forever.

Fix syntax here too in case we need to revive it.

Make the ppp-linkup script understand both address families.

Bind the state killing to the interface they should kill the states so that it does not impact other services like in #1421

Make sure this does not operate on empty parameters, and also log when removing states.

Just break states based on the remote host ip and not with localip. The later might be the same as address used by other services and might interrupt them

Put a netmask of /32 to all parameters of -k/-K/-b of pfctl to avoid any issues.

Kill states from the previous ip the link had on all mpd consumers. Resolves #1629

Fix test for tun device, -f fails because it's a char device, not a regular file. -e works.
