A secure AES key token contains the master key verification pattern
of the master key it is encrypted with. Add a function to obtain the
master key verification pattern of a secure key token.

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).

To reduce the size of the zkey.c source file, all routines that
deal with secure keys are moved to a new source file pkey.c.
