Ok, I've reworked my previous patches; attached is version 2 of support
for multi-volume DDF configurations.  This patch is entirely
self-contained within the DDF metadata handler and requires no changes
to the core code.  Other than that, it's pretty much the same thing as
the first iteration.  It's known to work against all of my DDF samples
as well as the Dell samples that Heinz sent me.
