    Introduce set_force_quit_flag and change type of sync_quit_force_run
    
    At the moment, handle_sigterm() in event-top.c does the following:
    
      sync_quit_force_run = 1;
      set_quit_flag ();
    
    This was used several more times in a later patch in this series, so
    I'm introducing (at Pedro's suggestion) a new function named
    'set_force_quit_flag'.  It simply sets sync_quit_force_run and also
    calls set_quit_flag().  I've revised the later patch to call
    set_force_quit_flag instead.
    
    I noticed that sync_quit_force_run is declared as an int but is being
    used as a bool, so I also changed its type to bool in this commit.
