[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.
