In order to display the correct language, timezone, airplane
mode and other settings on the decrypt screen, a copy of those
settings needs to be stored unencrypted so the framework can
query them. This adds support to vold to store up to 32
property like key/value pairs that are not encrypted.

This vold command returns 0 if the given password matches the password
used to decrypt the device on boot. It returns 1 if they don't match,
and it returns -1 on an internal error, and -2 if the device is not encrypted.
Also check the uid of the sender of the command and only allow the root and
system users to issue cryptfs commands.
