Subject: * eval.c (error_handle): no message when exiting by signal.

* eval.c (ruby_cleanup): re-send signal.  [ruby-dev:30516]

* eval.c (rb_thread_interrupt): instantiate SignalException.

* eval.c (rb_thread_signal_raise): now takes signal number instead
  of signal name.

* intern.h (rb_thread_signal_raise, ruby_default_signal): prototypes.

* signal.c (esignal_init): takes a signal number and an optional
  signal name.

* signal.c (interrupt_init): pass SIGINT always.

* signal.c (ruby_default_signal): invoke system default signal
  handler.

* signal.c (rb_signal_exec, trap): handle SIGTERM.  [ruby-dev:30505]
