Log the ciaddr and requested-ip-address if exists. Previously the message
said it logged yiaddr sent by the client, but the client doesn't set the
yiaddr.

This patch runs the database parser last (after subnets have been parsed).
This allows, for example, to access the subnets staging configuration
when leases are being loaded from disk.

Merge the changes for 3759 into the master branch

Update the LFC check in the server to check see that neigher
the finish file nor the copy file exists before moving the current
lease information to the copy file.

Add tests to verify that the current file isn't moved if either
of the two files exist.
