grapher: start of a dialog for displaying active stap processes

The names of active scripts are displayed in a list; mock buttons
suggest being able to stop and restart them.

* grapher/processwindow.glade: new file
* grapher/Makefile.am: add processwindow.glade to installed files
* grapher/StapParser.hxx (StapProcess): new class
  (StapParser): factor out members that are now in StapProcess
  (ioCallback): Use the new childDied signal instead of aborting the
   whole grapher when a child dies.
* grapher/grapher.cxx (ProcModelColumns, ProcWindow): classes for
  displaying stap process window.
  (GrapherWindow::on_menu_proc_window): new function
