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.

Secure keys of type CCA-AESCIPHER require a CEX6C or newer crypto
card. Also check for the minimum required card level during cross
checking of APQNs. Also display the card level in the APQN report.

Add a utility function to cross check the master keys of a set of
APQNs. It checks for valid master keys in the CURRENT and OLD
master key registers, as well as newly loaded master keys in the NEW
register. It issues information and warning messages for various
findings and also indicates improper master key setup to the caller.

Add a utility function to print the master key verification patterns
of a set of APQNs. This allows the user to visually check which
master keys are set on which APQNs.

Add a utility function to iterate over all available APQNs of
type CCA-Coprocessor. This function is required for various
future enhancements.

With recent changes in the zcrypt device driver, the master key verifi-
cation patterns of the AES master key of am APQN can be obtained by
reading the sysfs attribute 'mkvps' of an APQN device of type CCA-
Coprocessor. The sysfs attribute can be found under
'/sys/devices/ap/cardnn/nn.mmmm/', where nn specifies the card number
in hex, and mmmm specifies the domain number on hex.
