[AUTOCHK] Add also support for scanning FATX volumes.
The Format(), FormatEx(), Chkdsk(), ChkdskEx() functions exposed by the
U*.DLL user-mode FS library dlls are different (and have different
prototypes) than the similarly-named functions exported by FMIFS.DLL .
In particular, what we used to call "xxxChkdskEx()" and "xxxFormatEx()"
in our U*.DLL libraries actually correspond more, from their arguments,
to the "Chkdsk()" and "Format()" functions in Windows' U*.DLL . Their
*Ex() counterparts instead take most of the parameters through a
structure passed by pointer.
On FMIFS.DLL side, while FMIFS!Chkdsk() calls U*.DLL!Chkdsk() and
FMIFS!ChkdskEx() calls U*.DLL!ChkdskEx() (and we do not implement these
*Ex() functions at the moment), both FMIFS!Format() and FMIFS!FormatEx()
call U*.DLL!Format() instead, while FMIFS!FormatEx2() calls
U*.DLL!FormatEx() (that we do not implement yet either) !!
To improve that, refactor the calls to these U*.DLL functions so as to
respect the more compatible prototypes: They contain the correct number
of parameters in a compatible order. However, some of the parameters do
not have the same types yet: the strings are kept here in PUNICODE_STRINGS,
while on Windows they are passed via an undocumented DSTRING struct, and
the FMIFS callback is instead a MESSAGE struct/class on Windows.
Finally, the MEDIA_TYPE parameter in U*.DLL!Format() is equivalent, yet
not fully 100% in 1-to-1 correspondence, with the FMIFS_MEDIA_FLAG used
in the corresponding FMIFS.DLL functions.
One thing to notice is that the U*.DLL!Format() (and the Ex) functions
support a BOOLEAN (a flag resp.) for telling that a backwards-compatible
FS version should be used instead of the (default) latest FS version.
This is used e.g. by the FAT FS, where by default FAT32 is selected
(depending also on other constraints like, the disk and the partition
sizes), unless that bit is set in which case, FAT16 (or 12) is used.
- Add support for the following command-line arguments: /k, /p (and a little bit
of /r), and add support for checking a particular volume.

- Slightly improve some messages.
- Get rid of legacy OpenDirectory() and simplify GetFileSystem().
