* ext/tk/tkutil/tkutil.c (tk_conv_args): forget to revert

  thread_critical and gc_disable when raise ArgumentError.

* ext/tk/tcltklib.c: add TclTkIp#has_mainwindow? method.
* ext/tk/lib/tk.rb: add Tk.has_mainwindow? method.
* ext/tk/lib/multi-tk.rb: add MultiTkIp#has_mainwindow? method.
* ext/tk/lib/remote-tk.rb: add RemoteTkIp#has_mainwindow? method.
* ext/tk/lib/multi-tk.rb: slave IP fail to exit itself when $SAFE==4.
* ext/tk/lib/multi-tk.rb: remove constants from MultiTkIp module to
  avoid access from external.
* ext/tk/lib/multi-tk.rb: check_root flag is ignored on slave IPs'
  mainloop.
* ext/tk/lib/multi-tk.rb: hang-up Tk.mainloop called on a slave IP
  with $SAFE==4.
* ext/tk/lib/multi-tk.rb: MultiTkIp#bg_eval_proc doesn't work
  properly.
* ext/tk/lib/multi-tk.rb: add MultiTkIp#set_cb_error(proc) and
  cb_error(exc) to log errors at callbacks on safe slave IPs.
* ext/tk/lib/multi-tk.rb: fail to get an available slave IP object
  when call Tk.mainloop in the block which is given to new_* method,
  because cannot finish initialize while the root widget is alive.
