unbound runs as nobody and cannot reload its configuration
when this file is only readable for root.

When there is a large number of leases, writing the file may
take a long time. When unbound is re-reading its configuration
in that time, the file might syntactically incorrect.
This change writes the file first and then moves it
to the right place in one transaction.

Before the bridge tries reading any existing leases from unbound
but this makes it difficult to destinguish between what is a DHCP lease,
static host entry or anything else.
This patch will change the bridge back to just remember what has been
added to the cache already which makes it easier to keep track.

If there are any invalid hostnames in the DHCP leases
table, we just skip them and do not create and RRs for
them.

This allows us to restart unbound and all DHCP leases
will be re-imported even if the unbound-dhcp-leases-bridge is
not restarted.
