s4 torture: Add new test to create a file with a lot of streams

Browse Source 
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.
