s4 torture: Add new test to create a file with a lot of streams
This tests how streaminfo deals with large buffers smbclient seems to have problems when the buffer size approaches the max data size. Also smbclient exposes no way to specify the max data size that is sent in a trans2 request. Instead it hardcodes in a much larger max than windows uses. For these reasons this test isn't actually run, but is more of a reference for how windows handles streaminfo buffers.
