*) API: New register_other_child() API (see http_main.h) which allows

     modules to register children with the parent for maintenance.  It
     is disabled by defining NO_OTHER_CHILD.  [Dean Gaudet]

  *) API: New piped_log API (see http_log.h) which implements piped logs,
     and will use register_other_child to implement reliable piped logs
     when it is available.  The reliable piped logs part can be disabled
     by defining NO_RELIABLE_PIPED_LOGS.  At the moment reliable piped
     logs is only available on Unix. [Dean Gaudet]
