vold: Bugfixes & cleanups
- Fix issue where container-names > 64 bytes were getting truncated in the
kernel. lo_name is only 64 bytes in length, so we now hash the container
id via md5
- Add 'dump' command to dump loop and devicemapper status
- Add 'debug' command to enable more detailed logging at runtime
- Log vold IPC arguments (minus encryption keys)
- Fix premature return from Loop::lookupActive() and friends
