[NTFS]
Bugfixing... Part 4/X:
- Fix a nasty bug in NtfsLookupFileAt() (how did it work before?). The name parsing was wrong (no progress was being made) and thus was leading to an infinite loop in directory browsing.
- Fix a lovely bug coming from a non-documented feature in NTFS. To properly read the MFT index, you've to apply a mask. Do this to properly handles MFT record. This fixes returned MFT index which allows resuse.
- Do not allow returning MFT records < 0x10 for now. Not sure whether it should be allowed, but so far, these are MFT special records, so let's forget about it. IIRC, they are available on Windows. But trying to chase another bug for the moment.

This does not fix yet directory enumeration.
