    grapher: integrate graph events from stdin with the stap process framework.
    
    This was the original way to do graphing and had bitrotted some.
    
    * grapher/StapParser.cxx (initIO): new catchHUP argument
      (ioCallback): Only disconnect signals, etc. on IN_HUP if catchHUP is
      true.
      (errIoCallback): Write error messages to stderr, not stdout.
    * grapher/grapher.cxx (StapLauncher::launch): Don't catchHUP on our
      stap process children.
      (ProcWindow::refresh): Display something reasonable for the stap
      "process" that is feeding stdin.
      (main): Use StapParser::initIO to initialize parser reading from
      stdin.

    grapher: more implementation stap process window
    
    The process arguments are displayed, and the "kill" button is
    insensitive when  a process is dead or nothing is selected.
    
    * grapher/grapher.cxx (ProcWindow _killButton, _restartButton,
      _stapArgsLabel, _scriptArgsLabel): new members
      (ProcWindow::ProcWindow): hook 'em up
      (ProcWindow::onSelectionChanged): Enable / disable kill button and
      display process arguments.
    * grapher/processwindow.glade: Replace bizzare handle window with a
      horizontal pane. Tweak various widget sizes.

    grapher: change SIGCHLD handling and exit cleanup
    
    The signal handler now calls waitpid() and writes the pid and status
    to its pipe.
    
    * grapher.cxx (ChildInfo): new class
      (handleChild): wait for zombies and write their status down the
      pipe.
      (ChildDeathReader::ioCallback): Read dead child's pid from signal
      handler pipe and emit signal.
      (ChildDeathReader::reap): delete
      (ChildDeathReader::Callback): delete
      (StapLauncher::StapLauncher): Connect to childDied signal.
      (StapLauncher setWinParams, reap, cleanUp): delete
      (onChildDied): new function that updates the parsers list when a
      child dies.
      (GrapherWindow): Remove ChildDeathReader::Callback base class
      (GrapherWindow::onParserListChanged): New function; exits if program
      is quitting and no parsers are left.
      (on_menu_file_quit): Kill all children; don't hide (and exit) unless
      there are no parsers.
      (main): Don't do any cleanup after Gtk loop exits.

      members for sigc connections.
      (initIo): New function
      (parsers, parserListChangedSignal): new variables
    * grapher/StapParser.cxx (ioCallback): disconnect signals when child
      dies
      (initIo): new function
    * grapher/grapher.cxx (StapLauncher): eliminate death callback in
      favor of childDied signal. Use global parsers list
      (ProcWindow::_listSelection): new member
      (ProcWindow::show, hide, onParserListChanged, onSelectionChanged,
      onKill): new functions
      (ProcWindow::ProcWindow): Set up cell renderer for status icon
    * grapher/processwindow.glade: labels for display script and stap arguments
