+RPC

+- The `dumptxoutset` RPC now returns the UTXO set dump in a new and
+  improved format. At the same time the `loadtxoutset` RPC now
+  expects this new format in dumps it tries to load. Dumps with the
+  old format are no longer supported and need to be recreated using
+  the new format in order to be usable.
