Improve dexdeps output.
This adds the list of referenced classes to the output. Previously it
only emitted fields and methods, so classes that were referenced by type
only (e.g. some dalvik annotation classes) weren't visible.
The XML output now more closely resembles the API files, having
distinct package/class tags. We no longer emit a return type for
constructors.
