[CIFS] Add definitions for remoteably fsctl calls
Browse files Browse the repository at this point in the history 
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.
