In test functions calling mbedtls_test_unhexify(), change the type of the associated parameters from `char*` to `data_t`. That way the `unhexify` operation is done by the test framework and not by the unit test code. Use for the new parameters of type data_t the name of the local variable that used to store the `unhexify` version of the `char*` parameter. Signed-off-by: Ronald Cron <ronald.cron@arm.com>
