6b1eeb4004 Fix DKEK import when no logged.
DKEK shall accept import even if it is not logged in. However, to store the DKEK, the PIN is used for MKEK, which is not available if it is nog logged in. I added a queueing system to store a pending DKEK after login.

Therefore, to import a DKEK, the user must import it AND call VERIFY command if it is not already logged in.

1c7bc18161 Added support for AES 512 bit key size.
AES XTS uses two keys. Therefore, XTS with 2 AES 256 implies 64 bytes key length.

00279da8d5 Adding Secure Lock to lock the device with a random 256 bit key.
This is an extra layer of security to avoid brute force attacks if PIN is too weak.
At every hard reset (on device plug), the device must be unlocked prior any other command. Once unlocked, the device can be used as usual.
