[USETUP] Diverse fixes for path handling.
- Convert almost all swprintf() into StringCchPrintfW() and wcscpy() into
StringCchCopyW();
- Explicitly add a trailing path separator to the
"\Device\HarddiskX\PartitionY(\)" paths
when they refer to FS directories (and not to partition objects);
- Remove useless (and half-buggy) "Remove trailing backslash" code.
With that, it is possible to install ReactOS in e.g. C:\ReactOS (as usual),
C:\ReactOS\dir1\dir2 (as many dirs as you wish), and also in C:\ (yes yes!).
But in that latter case, a strange bug related to the registry arises...
Additionally:
- Adjust some comments;
- Add some debugging DPRINTs;
- The SetInstallPathValue() is part of the big hack I've mentioned in f51faa4a
(r74709).
