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
