Subject: [PATCH] DEVEL15-windows-ioctl-path-availability-20070614

fix cm_IoctlPathAvailability to return the current volume state.
0, CM_ERROR_ALLBUSY, CM_ERROR_ALLDOWN, CM_ERROR_ALLOFFLINE

modify fs.c to generate messages when the errors are received.


(cherry picked from commit e8fa4d0e40c2a4352010986f82ac2fbfe8b8ae3e)
