Create a FuseDataProvider base class
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
