Bug 585591 – Starting/stopping drives
Add API for starting/stopping drives. This new API will enable
GVolumeMonitor and GVfs implementations to add support for the
following features
1. Powering down external hard disk enclosures / drives
2. Starting/stopping multi-disk devices (such as RAID/btrfs/ZFS)
3. Connecting/disconnecting iSCSI devices
4. Reacting to the user pressing e.g. the "remove drive" button on
a IBM/Lenovo Ultrabay: http://www.thinkwiki.org/wiki/Ultrabay
See the bug for the corresponding GVfs and Nautilus changes.
