The basic model is that image drivers declare a fp_img_driver structure rather than a fp_driver struct. fp_img_driver will contain primitive imaging operations such as 'scan finger and return image'. The imgdev layer will generically implement the primitive fp_driver operations, and the imgdev layer will fix up the enroll/verify/etc pointers at driver registration time. Removed const from all fp_driver declarations, as these are now modified dynamically in the case of imaging drivers.
