ext/tk/tcltklib.c: adjust nesting

* ext/tk/extconf.rb: check for rb_thread_alive_p and
  rb_thread_check_trap_pending.

* ext/tk/tcltklib.c (rb_thread_alive_p, rb_thread_check_trap_pending):
  define substitutions if not available.

* ext/tk/tcltklib.c (lib_eventloop_core, lib_eventloop_ensure),
  (lib_thread_callback, ip_rbUpdateCommand, ip_rbVwaitCommand),
  (ip_rbTkWaitCommand, call_queue_handler, eval_queue_handler),
  (invoke_queue_handler): adjust nesting.
