* native/jniwrapper/jni_io_stream.cpp
  (InputStream::get_global_stream, InputStream::get_stream,
   OutputStream::get_global_stream, OutputStream::get_stream):
   Return a NULL stream if the wrapped object is null.

* native/org_apache_subversion_javahl_util_PropLib.cpp
  (Java_org_apache_subversion_javahl_util_PropLib_checkNodeProp):
   Reimplement in the new style, incidentally fixing a bug where
   we did not properly NUL-terminat the propery value string that
   was converted from the Java byte array.
