Deploy ap_sub_req_lookup_dirent() for the main loop.  Note we _really_
  need to further optimize this code, there are dozens of perhaps unnecessary
  stat calls, and meaningless #ifndef OS2 protections around apr_lstat()'s.
  OS2 has lstat (It's simply stat()) so we should pull the os-specific cruft.
