Prior to this change, Settings was using volume.getPath().getTotalBytes() to calculate the total, which includes the user-accessible storage, but not the internal partitions. As such, the total displayed was often missing many GBs (for example, in a 32GB device, it could display "12.09GB of 25.01GB used". This change fix this problem by using the total size and creating a "System" section containing the "missing" storage. BUG: 24128505 Change-Id: Ic35cd7c8406eff16ac1d97c4b4c233ecde64a6e1 ** Cherrypicked from master - DO NOT MERGE **
