420387a7a5 bitlk: Ignore unknown metadata entries for unsupported VMKs 
VMKs (keyslots) protected with a smart card or TPM have some
additional metadata entries that are currently unkwnon. We can
safely ignore these because we don't support unlocking the device
using these VMKs so we should still be able to parse the metadata
and unlock the device using other VMKs like the recovery password.

834059ddfa Do not hardcode number of DM segments for BitLocker devices 
Sometimes there is no gap between the metadata so we don't want to
create a dm-crypt segment there.

5ec2fbcd38 Allow empty passphrases when opening BitLocker devices 
It's probably not possible to create a BitLocker device with an
empty passphrase but we want to support it. And it's definitely
better to ask for the passphrase again instead of returning
ENOMEM.

83934bdcf3 Clarify LUKS2 error message related to reencryption. 
Original messages could evoke reencryption is currently
in progress. That was inaccurate because code only
detected flag marking such device is in transition state
from metadata pov. We should not imply anything about
running processes. That's detected via reencryption locks.

5e1d1e1850 Add missing validation when unlocking keys for reencryption. 
We missed keyslot json validation when unlocking all keys necessary
for reencryption. Also assign appropriate verified digest id to
keys in volume key structure.

e52c8e148c Remove unnecessary query for volume key size. 
In fact we need only stored key size in examined keyslot. It's valid for
default segment volume keys and in case of non-default segment
keys it always returns -1 and fallbacks to stored key size query
instead.
