Update headers to update various SMB3 ioctl definitions

MS-SMB2 Section 2.2.31 lists fsctls.  Update our list of valid
cifs/smb2/smb3 fsctls and some related structs
based on more recent version of docs.  Additional detail on
less common ones can be found in MS-FSCC section 2.3.

CopyChunk (server side copy, ie refcopy) will depend on a few
of these
