[CIFS] Add definitions for remoteably fsctl calls
There are about 60 fsctl calls which Windows claims would be able to be sent remotely and handled by the server. This adds the #defines for them. A few of them look immediately useful, but need to also add the structure definitions for them so they can be sent as SMBs. Signed-off-by: Steve French <sfrench@us.ibm.com>
