- Introduce code that detects the filesystem of a (mounted?) partition, using NtQueryVolumeInformationFile() with FileFsAttributeInformation class,
aka. rely on ReactOS itself (kernel, storage stack, filesystem drivers...) to recognize the FS on a partition that should normally be seen by the system.
This currently half-works for whatever reason (to be insvestigated), while it works on Windows.
- Fix few comments & a function parameter name.
- Use NT string pointer types.

- ConcatPaths that concatenates paths (or a path and a file name);
- OpenAndMapFile (resp. UnMapFile), whose purpose is to open a file and map it in memory (resp. unmap it from memory).
- Add extra optional parameters to DoesPathExist and DoesFileExist: an optional "RootDirectory" handle and, for DoesFileExist only, an optional PathName.
- Close the opened file handles only on success.

- Path must not contain whitespace characters.
- Path must be at least 2 characters long.
- Path must start with a backslash.

- Path components must not end with a dot.

This avoids the open failing on certain file systems where GENERIC_WRITE access would be denied
for a readonly file.
This is an addendum to 82f44a2.
CORE-14158
In such situation, try to drop the readonly attribute before overwritting the file.
This fixes setup not being able to overwrite FAT bootcode when reusing a FAT partition
already installed without reformatting.
CORE-14158
it only perform a full check if dirty bit is set (which should never happen *cough*).
This is needed because otherwise, ReactOS installation takes forever when IopParseDevice is gone
due to slow ChkDsk.
