Arc Wang 044c91cc70 Query storage size instead of calculate size of installed APP
From android S, Storage Settings show files of images/videos/audios
category instead of installed APP of each category. So it's
necessary to change the way to calculate size information.

This change also
- StorageItemPreference shows changing storage size units instead
  of fixed GB. It helps UX for categories of only small size files.
- Query media provider for size of Documents and others.
- Query media provider for size of Trash.
