STABLE14-windows-unix-mode-bit-enforcement-20070102

When the Unix mode bits do not include the write bit (0200), then the
file is reported to Windows as read-only.  This also prevents the
acquisition of write-locks.  It should also prevent deletion but the
code in cm_HaveAccessRights() did not remove the PRSFS_DELETE privilege
from the reported rights.
