Since emulated external storage paths differ based on execution
context, carefully fix up paths for various use-cases:
1. When sending paths to DefaultContainerService, always scope
OBB paths as belonging to USER_OWNER.
2. When sending paths to vold, always build emulated storage paths
visible to root.
3. Always use the original untouched path when talking with apps.
Mount OBB containers using shared app GID, so that an app can read
the mount point across users.
Handle legacy paths like "/sdcard" by resolving the canonical path
before sending to MountService. Move tests to servicestests, and
add tests for new path generation logic.

External storage volumes that were emulated+encrypted needed to have
their encryption mapping removed so that it doesn't try to encrypt the
volume after formatting them.
This just wires through an argument through vold, and assumes that vold
will do the right thing even if there is no encryption mapping set.

* Implement the decryptStorage() method on the Mount Service.
This method makes the calls into vold to decrypt the encrypted
volumes and mount them.

Rearrange structure of MountService handling of OBBs to be entirely
asynchronous so we don't rely on locking as much. We still need the
locking to support dumpsys which has been improved to output all the
data structures for OBBs.
Added more tests to cover more of the error return codes.
Oh and fix a logic inversion bug.

Add a callback for users of the StorageManager API to be able to receive
notifications when the requested operation completes for mountObb and
unmountObb.
Add NDK API to get to ObbInfo like the Java API has.
Also update the docs for the API and remove the "STOPSHIP" comments.

Remove auto-generated AIDL files and replace them with manually edited
.java and .cpp/.h files so that binder calls can be made from either
Java or C++.
Update the makefiles to not attempt to generate the AIDL files and also
remove the old auto-generated .java files.
Put all the storage-related C++ things in libstorage so that we don't
pollute other libraries.
