[fireball] 43343: [fastfat_new] - Add two names to an FCB - a short name, and a long name. - Start implementing FatSetFcbNames, currently deals with short names only. - Implement Fati8dot3ToString, with most of the code actually #if0ed, because FullFAT already does this conversion.

[fastfat_new]
- Add two names to an FCB - a short name, and a long name.
- Start implementing FatSetFcbNames, currently deals with short names only.
- Implement Fati8dot3ToString, with most of the code actually #if0ed, because FullFAT
already does this conversion.
