Ingo Franzki a86e41a518 zkey: Add 'convert' command to convert keys from one type to another
Add a new 'convert' command. It allows to convert a secure key from
one key type to another. Currently only keys of type CCA-AESDATA can be
converted to CCA-AESCIPHER.

Ingo Franzki 0d9e42264d zkey: Add key checks when importing a CCA-AESCIPHER key
Perform extended checks on a secure key that is imported into
the key repository. Warn the user if the imported key is by
any means insecure, e.g. has been originally created in an
insecure way. Prompt the user to continue the import if a
potential insecurity is detected.

Ingo Franzki b47007b8ac zkey: Allow to specify the key type with the generate command
The zkey generate command allows to specify the --key-type|-K
option to specify the key type. If not specified, then the
default is CCA-AESDATA.

The zkey list command now accepts option --key-type|-K type
to filter the displayed keys by key type. If not specified,
then all key types are displayed.

Ingo Franzki 95c7258ea7 zkey: Separate and rework CCA host library loading
As preparation for future changes, rework the loading of the
CCA host library so that the exported symbols are not passed
individually to the functions that use it. Pass a structure
that contains all entry points of all loaded CCA functions
instead. This will make it easier to add further CCA functions
at a later time.

Also add a version query for the CCA host library since some
future functions might be dependent on the library version.

While at it, separate the CCA related functions and definitions,
and move them into a separate source file (cca.h/cca.h).

Ingo Franzki f97d048643 zkey: Allow to associate non-existing APQNs with a key
Add option --no-apqn-check to the generate, import, change, and
validate commands to disable checking of the specified APQNs.

With this option a currently non-existing APQN can be associated
with a key. This is useful to associate APQNs that exist only on
other systems, such as disaster recovery systems, but not on the
current system. When generating keys, at least one of the specified
APQNs must be available to generate the key.

Ingo Franzki 11bfa1d3c8 zkey: Add open and format options to the cryptsetup command
For LUKS2 volumes the cryptsetup command currently generates
'cryptsetup luksFormat' commands, but for plain mode volumes it
generates 'cryptsetup plainOpen' commands.

With the --open option it can now also generate 'cryptsetup luksOpen'
commands for opening LUKS2 volumes. With the --format option you can
limit the generated commands to only generate 'cryptsetup luksFormat'
commands for LUKS2 volumes, and skip plain mode volumes.
The default behavior (i.e. if none of the two options specified),
remains the same as before.

Ingo Franzki 3ed8ab4e2a zkey: Add common passphrase options for crypttab command
When generating crypttab entries for LUKS2 volumes, allow to
specify common passphrase options like --key-file, --keyfile-offset,
--keyfile-size and --tries and pass those to the generated crypttab
entries.

Note that not all distributions support the keyfile-offset and
keyfile-size options in crypttab entries.

Ingo Franzki 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'.
