NTFS driver improvments :

Browse source 
- Implemented NtfsFsdDispatch to dispatch some IO requests (use it with implemented functions that need it)
- Implemented NtfsIsIrpTopLevel (From Rajeev Nagar), NtfsAllocateIrpContext
- Added more checks
- Renamed functions that are called by IO to NtfsFsd* (similar to Windows NTFS driver)
- Use NTAPI instead of STDCALL to have MSVC compatibility, thanks to Hervé
- Reorganized functions order with increasing index
- Updated files headers
