Georges Basile Stavracas Neto 67125ae4e0 placesview: implement available space 
GtkPlacesView is a widget to display locations
in the computer, such as root ("/") and volumes,
separating the persistent devices from removable
ones.

From the latest mockups[1], GtkPlacesView would
display the available space of local drives like
partitions. This, however, is not implemented in
the current codebase.

Fix that by implementing the measurement of disk
space, and adding a new property GtkPlacesView::show-disk-usage
which controls the visibility of measured disks.

* @Short_description: Widget that displays persistent drives and manages mounted networks
* @Title: GtkPlacesView
* @See_also: #GtkFileChooser
*
* #GtkPlacesView is a stock widget that displays a list of persistent drives
* such as harddisk partitions and networks. #GtkPlacesView does not monitor
* removable devices.
*
* The places view displays drives and networks, and will automatically mount
* them when the user activates. Network addresses are stored even if they fail
* to connect. When the connection is successful, the connected network is
* shown at the network list.
*
* To make use of the places view, an application at least needs to connect
* to the #GtkPlacesView::open-location signal. This is emitted when the user
* selects a location to open in the view.
