Progress towards FBE and adoptable storage.

Offer to adopt storage devices on FBE devices, but keep it guarded
behind a system property for now, since we still need to work out key
storage details.

When migrating shared storage, leave user-specific /data/media
directories in place, since they already have the needed crypto
policies defined.

Enable journaling, quotas, and encrypt options when formatting
newly adopted devices.  installd already gracefully handles older
partitions without quota enabled.
