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

Browse source 
* eval_error.h (error_handle): no message when exiting by signal.

* 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_f_kill): use NUM2PIDT instead of NUM2INT.

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

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

* thread.c (rb_thread_signal_exit): since rb_make_exception() calls
  #exception method, rb_class_new_instance() is not needed here.

* yarvcore.h (struct rb_vm_struct), eval_jump.h (terminate_process):
  exit_code is no longer stored in VM.
