[Development] moving some SystemInfo stuff into qtbase (was Re: QtDriveInfo module in Playground)

[Tony Van Eerd]

There was some work going on inside BlackBerry to revamp QSystemStorageInfo.  Last version I saw had:

QDrive:
- similar to QDir (not a QObject!).
- construct from URI/path (ie "dev/sda1" or "D:\")
- mount/unmount/is-it-mounted/list-of-mount-points/etc
- total/available space

QDriveWatcher:
- QObject, constructed from a QDrive (or uri/path)
- Signals when a particular drive is mounted/unmounted
- also signals on activity-state changes (ie for SD Cards 'busy', etc)

QDriveListWatcher
- get list of drives
- signal when drives are added/removed


Maybe we can get it put up for review...


P.S. note that Windows (NTFS) now has "real" mount points, as well as D:,E:,...
