[KERNEL32]

[KERNEL32]
- Implement the internal functions: GetVolumeNameForRoot(), BasepGetVolumeNameFromReparsePoint(), BasepGetVolumeNameForVolumeMountPoint() that allow querying the volume name (GUID form) given a volume root
- Reimplement GetVolumeNameForVolumeMountPointW() with the new internal function BasepGetVolumeNameForVolumeMountPoint() this fixes a few bugs and adds supports for reparse points
- Reimplement GetVolumeNameForVolumeMountPointA() to make it w2k3 compliant

Note that I dropped copyrights in the header, as everything got reimplemented
