Log:
[CMLIB]
- memcpy --> RtlCopyMemory
- Remove a __debugbreak()
- Improve a bit the DPRINT that is displayed when a corrupted hive is loaded.
- Fix a comment.
- Implement saving the hive file name in the hive itself. According to what windows does
(just open an existing hive file with your preferred hex editor 8^) ), you can see that it
copies the last 31 unicode characters of the path, and terminate it by a NULL.
[NTOS]
Remove unneeded cast.
