Log:
[KERNEL32]
- Implement BasepOpenFileForMove() used by PrivMoveFileIdentityW(), with its Windows bugs
- Implement PrivMoveFileIdentityW()
Not sure yet why Windows implementation exposes a sharing violation during our API test.
Our absence of sharing violation looks more legit...
To be investigated.
