s3:smbXsrv.idl: add smbXsrv_open* structures

struct smbXsrv_open will represent a SMB 1 or SMB 2
open file handle, while 'files_struct' will be changed
to handle just the protocol independent glue for the SMB_VFS layer.

Note: the format is not stable yet, we need to add more things
      when we start to support durable handles.
