Added a library containing GUIDs for PnP notifications

[BUGCODES]
Added missing bugcheck code for PnP manager

[NTOSKRNL]
- Implemented FsRtlNotifyVolumeEvent()
- Implemented IoReportTargetDeviceChange(), IoReportTargetDeviceChangeAsynchronous()
- Craplemented PpSetCustomTargetEvent() to match our actual PnP manager notifications system. This is to be rewritten
- Added support for custom notifications in IopNotifyPlugPlayNotification()
- Added use of FsRtlNotifyVolumeEvent() in RawUserFsCtrl() to notify volume state changes
- Added use of IoEvent library to ntoskrnl

[FASTFAT]
- Added use of FsRtlNotifyVolumeEvent() when successfully mounting a volume

Finally, purpose of that patch is to implement volumes events notifications. Behaviour and implementation is correct till PpSetCustomTargetEvent(). The PnP notifications manager should be rewritten to match Microsoft's one. Furthermore, it appears that in Windows, those notifications are asynchronous.
