Fix https://bz.apache.org/bugzilla/show_bug.cgi?id=64074
InputStreams for directories obtained from resource URLs now return a
directory listing consistent with the behaviour of FileURLConnection.
In addition to restoring the behaviour that was lost as a result of the
introduction of CachedResourceURLConnection, it expands the feature to
include packedWARs and to take account of resource JARs.
