As an optimization, installd is now moving previously-installed
applications between attached storage volumes.  This is effectively
copying to the new location, then deleting the old location.

Since OAT files can now live under /data/app directories, we also
need the ability to relabel those files.

deviceidle service should be accessible to all non third-party apps.

This enables access to gatekeeperd for anybody who invokes Android
framework APIs. This is necessary because the AndroidKeyStore
abstraction offered by the framework API occasionally communicates
with gatekeeperd from the calling process.

Move all key management into vold
Reuse vold's existing key management through the crypto footer
to manage the device wide keys.

Use ro.crypto.type flag to determine crypto type, which prevents
any issues when running in block encrypted mode, as well as speeding
up boot in block or no encryption.

Users can pick files from vfat devices through the Storage Access
Framework, which are returned through ParcelFileDescriptors.  Grant
apps write access to those files.  (Direct access to the files on
disk is still controlled through normal filesystem permissions.)

Raw physical storage devices are mounted by vold under /mnt/media_rw
and then wrapped in a FUSE daemon that presents them under /storage.

Normal apps only have access through /storage, but platform apps
(such as ExternalStorageProvider) often bypass the FUSE daemon for
performance reasons.
