Dag-Erling Smørgrav 401465d8ea Move main() from libcryb-test to the test program.
Instead of having libcryb-test provide main() and assume that the test program defines t_prepare() and t_cleanup(), have libcryb-test provide a t_main() function which the test program calls with pointers to its prepare and cleanup functions.
