Please review a fix for a missing entry in the mapfiles.  The missing entry point caused the closing of unreferenced FileDescriptors to be skipped. Looks good.

The tests for FileInputStream, FileOutputStream, and RandomAccess file unreferenced FileDescriptors have been updated to verify the raw fds have been closed. closeCounter is incremented before super.close(). That is good enough for the original test as it's just checking that close is called. I'm just wondering if the test methods now need to poll FileDescriptor::valid or wait until ffd is -1 to ensure to avoid a race with the getOpenFileDescriptorCount.
