Review request for Plasma and Christopher Blauvelt.


Summary
-------

Currently, the soliddevice data engine use either statvfs() or statfs() for determine the free space on a mount point.
This, other than requiring per-OS code which does not cover all the OS KDE supports (for example Windows), is already wrapped in a nice API in kio, the class KDiskFreeSpaceInfo.

The proposed patch applies this class to the soliddevice data engine, although making it depend on kio.

Looks reporting the correct value for mounted mount points, when queried via plasmaengineexplorer.
