dnsmasq: add dhcp-script hook for other packages Adds a script which acts as a hook for when dnsmasq creates/destroys a lease, or completes a TFTP file transfer. The hook loops through scripts in appropriate directories inside '/etc/hotplug.d', executing each one with the same arguments supplied by dnsmasq. In case dnsmasq is jailed by ujail the dhcp-script hook will not work as expected as ujail does not yet support executing a script within a jail.
