  Fix ApacheBench for the apr_initopt/apr_getopt change.  This illustrates
  abusing the apr_getopt_t for direct access at the working structure, just
  as we did with the global vars.  By my global search, there should be no
  more apr_opt*** symbols out there.

- Log proper error message instead of error code on failure
- In case of error caused by an invalid file name, don't return an empty

- Avoid using the very expensive ap_os_systemcase_canonical_filename()
  unless it's truely necessary.
