The output C code was made to use ERR_func_error_string() to see if a
string table was already loaded or not. Since this function returns
NULL always, this check became useless.
Change it to use ERR_reason_error_string() instead, as there's no
reason to believe we will get rid of reason strings, ever.
To top it off, we rebuild all affected C sources.

This has been long overdue.
Note that this does not join the X509 and X509V3 error modules, that
will be too many macro changes at this stage.
