[NTOS]: Have I/O Manager Volume Device Objects register with the Power Manager so that they can receive dope.
[NTOS]: Reimplement NtShutdownSystem. [NTOS]: Implement NtSetSystemPowerState for the shutdown/reboot cases. [NTOS]: Use the dope from the volume device objects to flush all writeable (non-floppy) devices. Pending hard-disk changes are now flushed to disks before shutdown. [NTOS]: Flush \\REGISTRY during shutdown. This flushes all pending changes. [NTOS]: Call into Cc to flush lazy writer during shutdown. [NTOS]: Stop killing processes on shutdown. The kernel should not be doing this. [NTOS]: Don't only shutdown disk file systems, but also cdrom and tape. [NTOS]: Don't only notify drivers of first-chance shutdown -- also parse the last-change shutdown list. [NTOS]: Reference drivers registering for shutdown notifications so that they remain loaded for them to get the notification at shutdown. [NTOS]: Notify drivers that have registered/opened the Power State callback. [NTOS]: A lot of the Po* power state code is highly simplified, but provides a good roadmap to anyone interested in this functionality long-term. svn path=/trunk/; revision=46004
