    thread.c: disable VM events when stack overflow
    
    * thread.c (ruby_thread_stack_overflow): disable VM events when
      stack overflow occurred; it causes another stack overflow again
      in making backtrace object, and crashes.
      [ruby-core:80662] [Bug #13425]
    increase timeout seconds.
    
    * test/ruby/test_trace.rb (test_trace_stackoverflow): on some platforms
      this test fails because of timeout.
    
    disable rewind hooks.
    
    * vm.c (hook_before_rewind): skip rewind hooks if err is SystemStackError
      because rewind hooks can cause stack overflow again and again.
    
    * thread.c (ruby_thread_stack_overflow): do not disable all hooks.
      Additionally, clearing ruby_vm_event_flags is not suitable way
      to disable hooks.
