[0.4.9][CDFS_NEW] -> [CDFS]

Browse source 
port back:
0.4.10-dev-615-g 45fd48bd0f [CDFS_NEW] -> [CDFS] No old driver, thus no new driver
0.4.10-dev-614-g 5795254933 [CDFS] Delete the old CDFS driver.

The new MS PL licensed one worked for several years fine for us now
even in the older releases.
So no need to keep our old unfinished one any longer within
the release-branches. They are no mausoleum.
This does *not* change, which driver is actually in use.
We do continue to use 1:1 the state of current releases/0.4.10

Routine Description:
This is the common routine for cleanup of a file/directory called by both
the fsd and fsp threads.
Cleanup is invoked whenever the last handle to a file object is closed.
This is different than the Close operation which is invoked when the last
reference to a file object is deleted.
The function of cleanup is to essentially "cleanup" the file/directory
after a user is done with it. The Fcb/Dcb remains around (because MM
still has the file object referenced) but is now available for another
user to open (i.e., as far as the user is concerned the is now closed).
See close for a more complete description of what close does.
We do no synchronization in this routine until we get to the point
where we modify the counts, share access and volume lock field.
We need to update the Fcb and Vcb to show that a user handle has been closed.
The following structures and fields are affected.
Vcb:
VolumeLockFileObject - Did the user lock the volume with this file object.
VcbState - Check if we are unlocking the volume here.
VcbCleanup - Count of outstanding handles on the volume.
DirNotifyQueue - If this file object has pending DirNotify Irps.
Fcb:
ShareAccess - If this is a user handle.

/*++
Routine Description:
This is the common routine for cleanup of a file/directory called by both
the fsd and fsp threads.
Cleanup is invoked whenever the last handle to a file object is closed.
This is different than the Close operation which is invoked when the last
reference to a file object is deleted.
The function of cleanup is to essentially "cleanup" the file/directory
after a user is done with it. The Fcb/Dcb remains around (because MM
still has the file object referenced) but is now available for another
user to open (i.e., as far as the user is concerned the is now closed).
See close for a more complete description of what close does.
We do no synchronization in this routine until we get to the point
where we modify the counts, share access and volume lock field.
We need to update the Fcb and Vcb to show that a user handle has been closed.
The following structures and fields are affected.
Vcb:
VolumeLockFileObject - Did the user lock the volume with this file object.
VcbState - Check if we are unlocking the volume here.
VcbCleanup - Count of outstanding handles on the volume.
DirNotifyQueue - If this file object has pending DirNotify Irps.
Fcb:
ShareAccess - If this is a user handle.
FcbCleanup - Count of outstanding handles on this Fcb.
Oplock - Any outstanding oplocks on this file object.
FileLock - Any outstanding filelocks on this file object.
Arguments:
Irp - Supplies the Irp to process
Return Value:
NTSTATUS - The return status for the operation.
