Steve, This patch adds code to allow us to do fsctl passthrough for fsctl types that need to pass data to the server. This not only needs to pass the blob to the server but also need to decode the access-type part of the fsctl code and change the arguments to the CREATE accordingly. The values for the access are from wireshark traces of win16 -> win16. For now I only implement the special handling we need for FILE_READ_WRITE_ACCESS. We can add the others as needed and as we we discover them while adding new functions to smbinfo.
