The fuse data provider for adb/sdcard shares common code and structures. This cl creates a FuseDataProvider base class and provides implementations for adb and sdcard. In the follow cls, we can kill the provider_vtab struct; and also add another implementation to parse a block map file and provides data. Test: unit tests pass, sideload a package, apply a package from sdcard Change-Id: If8311666a52a2e3c0fbae0ee9688fa6d01e4ad09
