This allows abandoned leases to be reclaimed if there are no
available free leases.
+- If a client explicitly requests a lease that's been abandoned, it's
+ probably the system that was answering pings on that address, so let it
+ have the lease.
+
+- Fix a bunch of type conversion errors that are flagged by the Solaris
+ C compiler.
