Enrollment tweaks

Browse Source 
upekts will need to know when the first enrollment stage is attempted for
the first time, so add an __enroll_stage counter which actually indicates
the next stage to enroll. -1 is a special value and it means 0 is next *and*
it is the initial attemt.

Added more debug output to the enroll handler.
Added new fp_enroll_status codes for too short or uncentered scans.

Changed the print_data allocator to consider the device rather than the
driver, this feels more natural. Added missing return value.

Make fp_enroll_status codes start at 1. 0 can now be used as a
special/temporary value by the drivers. Also check that we aren't exceeding
the number of enroll stages.

Also add a missing exit() call to the verify example and update for the
above.
