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. Change-Id: Idf0611f74b56c1026c45742ca82e0c26e58828fe
