Add the QStorageInfo class
Allows to retrieve information about mounted volumes such as label, total/available size, filesystem type and so on. Possible use cases are: - allows to do checks about filesystem before performing actual operation (such as available/maximum volume size) - allows to retrive information about volume that can be shown in file dialogs - allows to retrieve volume for specific path and check if two or more paths belong to the same volume or not [ChangeLog][QtCore] Added QStorageInfo class to retrive information about mounted volumes and drives Change-Id: Ibf9c2e6b53ef39c5605894a4422acdbbca4030c4 Reviewed-by: Shawn Rutledge <shawn.rutledge@digia.com>
