This was a little messy because of all of the vfs modules I had to
touch.  Most of them were pretty straight forward, but the streams
modules required a little attention to handle smb_filename.  Since the
use of smb_filename enables the vfs modules to access the raw,
over-the-wire stream, a little bit of the handling that was being done
by split_ntfs_stream_name has now been shifted into the individual
stream modules.  It may be a little more code, but overall it gives
more flexibility to the streams modules, while also allowing correct
stream handling.

I'm not certain if the dummy pointer is needed in struct vfs_fsp_data,
but I added it to be consistent with the comment below.

The vfs_prealloc module makes use of the now redundant fd parameter for
SMB_VFS_FTRUNCATE(), instead get the fd from the files_struct.

Patch for Samba 3.2 Test branch below.
