Subject: [PATCH 3/9] Fix broken detection of null cipher in LUKS2.
This bug enabled to create LUKS2 keyslots encrypted by
cipher_null when explicitely requested by user. LUKS2
was never meant to allow keyslot encryption with
cipher_null. cipher_null is meant for debug purposes
only as a segment cipher.

Subject: [PATCH 6/9] Replace bogus cipher_null keyslots before reencryption.
By mistake LUKS2 allowed keyslots 'not-so-encrypted' by
cipher_null (only explicitly requested by --cipher or
--keyslot-cipher parameters). If we encounter
such old key during reencryption let's replace the cipher
for new keyslot with default LUKS2 keyslot cipher.
