This adds a new switch try-empty-password. If set and none of PKCS#11 or key files work, it is attempted to unlock the volume with an empty password, before the user is asked for a password. Usecase: an installer generates an OS image on one system, which is the booted up for the first time in a possibly different system. The image is encrypted using a random volume key, but an empty password. A tool that runs on first boot then queries the user for a password to set or enrols the volume in the TPM, removing the empty password. (Of course, in such a scenario it is important to never reuse the installer image on multiple systems as they all will have the same volume key, but that's a different question.)
