1f07a41d5a zkey: Add volume-type property to support LUKS2 volumes
Allow to specify a volume-type for a key. This applies to all
associated volumes. The volume type can be either 'plain' or
'luks2'. New keys created will default to 'luks2', but existing
keys that do not have a volume-type property default to 'plain'
for compatibility reasons.

The volume type 'luks2' is only available when the define
HAVE_LUKS2_SUPPORT is set in the makefile. This is set only
when libcryptsetup version 2.0.3 or newer is available
at build time. If the define is not set, the volume-type
option is not available to the user, and the volume-type of
a key defaults to 'plain'.

512b47c004 zkey: Add key verification pattern property
Store a verification pattern in the properties file along
with the secure key. The verification pattern allows to identify
the inner key even when the secure key is no longer valid.

672548ce30 zkey: Fix generate and import leaving key in an inconsistent state
When a volume or APQN association is made while generating or
importing a key, and a duplicate association is detected, then
this may leave the key in an inconsistent state.

344965bd29 zkey: Fix APQN validation routine
When a zkey generate or change command is used to associate one
or multiple APQNs the command succeeds, but no key is generated
and no APQNs are associated, because the return code returned by
_keystore_apqn_check() is wrong.

The APQN check routine as well as the properties helper functions
do not free all memory that they allocated.

c944f23d7e zkey: Add keystore implementation
Add a keystore implementation that stores secure AES keys in a
key repository, located in a directory, e.g. '/etc/zkey/repository'.
The keystore allows you to generate, validate, re-encipher, modify,
list, delete, etc secure keys.
