Stop encryption when battery is low, mark position, and continue on reboot. Note - support for multiple encrypted volumes removed as no devices seem to exist with an fstab that uses this feature. If you want support for such a device, contact me and we will re-add it with appropriate testing. Bug: 13284213 Change-Id: I1f7178e4f7dd8ea816cbc03ab5c4f6543e98acaa
