Changes with Apache 2.0.26-dev

  *) Introduce ap_directory_walk rewrite (with further optimizations

     required) to adapt to the ap_process_request_internal() changes.

     Optimized so subrequests and redirects now reuse previous section 

     merges, until we mismatch with the original directory_walk, and

     precomputed r->finfo results will cause directory_walk to skip

     the most expensive phases of the function.  [William Rowe]

  *) Allow ApacheMonitor to connect to and control Apache on other 

     WinNT/2K machines.   [Mladen Turk <mturk@mappingsoft.com>]
