[SETUPLIB][REACTOS][USETUP] Split FS-volume-specific functionality from partitions
(#7258)
CORE-13525
This greatly helps in reducing code complexity in some areas: code that
previously iterated over all partitions of a given disk, just to find
which ones were partitioned and contained a valid file system, now just
have to iterate over mounted volumes.
See in particular, `lib/utils/osdetect.c` and `lib/fsutil.c` .
- Remove FORMATSTATE "Preformatted" enum value;
- Cleanup osdetect code after introducing Volume support;
- Some simplifications for FormatState.
- Differentiate between 'new' partition and 'new' volume:
* "New" partition: it has been created and added in the cached list,
but not yet actually written into the disk.
* "New" volume: newly-created volume (may be backed by a partition or
not), not yet formatted. May exist on either new, or not new partition,
or elsewhere.
- Cache partition and volume NT device names.
These do not change across repartitioning operations, as long as the
partition or the filesystem volume hasn't been deleted/recreated.
This avoids doing \Device\Harddisk%u\Partition%u sprintf's everytime
we need to retrieve the given partition or volume device name.
When a partition/fileysystem volume is "virtually" created (i.e. in
the partition list, but not yet committed to disk and exposed to the
OS), no device partition number and device name are available yet.
In particular, validate that no manipulation of \Device\HarddiskM\Partition0
(i.e. the whole disk) is being made.
