[SETUPLIB][USETUP] Introduce a 'SetupLib' library. CORE-13544 - Create the beginnings of a "setuplib" library, whose aim is to be shared between the (currently existing) 1st-stage text-mode installer, and the (future) 1st-stage GUI installer. - Finish to split the GenList and PartList codes into their UI part, which remain in usetup, and their algorithmic part, which go into setuplib. - Move SetMountedDeviceValue into the PartList module. - Split the FileSystem list code into its UI and the algorithmic part (which goes into setuplib under the name fsutil.c). * The algo part is meant to be able to manage the filesystems available on the running system, similarly to what is mostly done (in scattered form) in fmifs, format, chkdsk / autochk codes... It also manages the partition filesystem recognition, using OS routines. * The UI part manages the FS list as it appears on screen, showing only the possible FSes that can be used to format the selected partition (a bit similar to what we do in the shell32's drive.c, etc...). - Adapt the calling code to these changes. - Remove some "host" code that was dating back from the dark old times. svn path=/branches/setup_improvements/; revision=74570 svn path=/branches/setup_improvements/; revision=74659

[FSLIB][FMIFS][AUTOCHK][SETUPLIB] Use more Windows-compatible (but not fully compatible yet) Format() and Chkdsk() ULIB functions. [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.

* PURPOSE: Filesystem Format and ChkDsk support functions.
[SETUPLIB][USETUP] Factor out the usage of FS provider structures. Similarly to FMIFS this structure should be private. Instead file-system names are passed to the helper functions, allowing to use the names returned by the FS drivers. The names are then internally mapped to the corresponding FS providers. In particular this allows to handle the "RAW" file-system and to assign the 'Unformatted' flag to partitions having this FS. Finally this helps us refining the checks performed to see whether the current "active" system partition uses a supported file-system.

[SETUPLIB][USETUP] Cleanup some code in USETUP. Redefine FormatPartition() and ChkdskPartition() helpers so that they wrap the needed init steps for formatting/chkdsk'ing. These helpers now accept a PPARTENTRY, together with the usual formatting/chkdsk parameters. The helpers now determine the actual NT path to use, and can perform the init steps on the partition before performing the actual operation. In particular, FormatPartition() is now made GPT-compliant. The partition type retrieved by FileSystemToMBRPartitionType() is now used as a hint for choosing FAT32 over FAT12/16, and only in the case of a MBR partition that is *NOT* a recognized OEM partition, it is used for updating the corresponding partition type. (OEM partitions must retain their original type.) The OEM partition types we (and NT) can recognize are specified e.g. in the Microsoft Open-Specification [MS-DMRP] Appendix B https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-dmrp/5f5043a3-9e6d-40cc-a05b-1a4a3617df32 Introduce an IsOEMPartition() macro to help checking for these types (its name is based on the Is***Partition() macros from ntdddisk.h, and from a dmdskmgr.dll export of similar name).
