This moves fstrim, obb and appfuse commands over to the new Binder interface. This change also separates creating/destroying and mounting/unmounting of OBB volumes, which means they finally flow nicely into the modern VolumeInfo/VolumeBase design. We now generate unique identifiers for all OBB volumes, instead of using a shady MD5 hash. Change all "loop" and "dm" devices to tag the kernel resources with a vold-specific prefix so that we can clean them up if vold crashes; there are new destroyAll() methods that handle this cleanup. Move appfuse mounting/unmounting into VolumeManager so it can be shared. Move various model objects into a separate directory to tidy things up. Test: cts-tradefed run commandAndExit cts-dev -m CtsOsTestCases -t android.os.storage.cts.StorageManagerTest Bug: 13758960 Change-Id: I7294e32b3fb6efe07cb3b77bd20166e70b66958f
