vold: allow to store key in a file on another partition
Add support for keeping the keys in a separate file on another partition,
for devices with no space reserved for a footer after the userdata filesystem.
Add support for encrypting the volumes managed by vold, if they meet certain
criteria, namely being marked as nonremovable and encryptable in vold.fstab.
A bit of trickiness is required to keep vold happy.
