Get the perchild MPM working better again. I have been able to pass

some file descriptors back and forth and serve requests, but this code is
still very experimental.

 RELEASE SHOWSTOPPERS:
 
-    * Perchild MPM doesn't build anymore.  This is still relying on the
-      BUFF code, which is no longer there.  This should just be modified
-      to do the passing in an input filter instead of relying on the
-      post_read_request phase.
-       Status: Ryan Volunteers
-
     * Root all file systems with <Directory /> for WIN32/OS2/NW permissions 
         Status: patch brought forward from 1.3.14
                 WIN32 and OS2 need review [William Rowe, Brian Harvard]
