CORE-16274
SETUPLIB:
=========
- Find the system partition initially when we create the list of
partitions.
- Split the old CheckActiveSystemPartition() helper in two helpers:
FindSupportedSystemPartition() and SetActivePartition(). This allows
simplifying slightly the former one, and allows the user, in an
interactive situation, to decide whether the "supported system
partition" found can actually be used or not.
- Remove the "OriginalSystemPartition" hack in the PARTLIST structure.
- Add a note regarding the SystemPartition member in PARTLIST.
USETUP:
=======
- Use the introduced helpers from above. If the "system" partition we
are going to use, in case we install ReactOS on a fixed disk, is *NOT*
the same as the original one (e.g. because it is detected to be not
supported by ReactOS...), display an informative screen to the user
and let him confirm whether or not he wants to change the partition.
If we install on a fixed disk, try to find a supported system partition
on the system. Otherwise if we install on a removable disk, use the
install partition as the system partition instead.
This allows providing a fix for CORE-16274.
