further address #986
Error codes now done until run_server_defaults(). Previous sections modified so that execution errors are added. Modified in compare_server_name_to_cert() ret --> subret. From the code perspective a clear distinction between passing an error code and a functional return code would be great. Still has to be determined whether it maybe better to rename ret into something different. Removed a stale code line in run_server_preference() for STARTTLS.
