* signal.c (sigexit): call rb_thread_signal_exit() instead of

  rb_exit().  [ruby-dev:26347]

* eval.c (rb_thread_signal_exit): a new function to exit on main
  thread.

* eval.c (rb_thread_switch): exit status should be retrieved from
  ruby_errinfo.

* eval.c (rb_f_exit): ensure exit(0) should call
  exit(EXIT_SUCCESS).

* missing/mkdir.c: remove. [ruby-core:05177]

* lib/delegate.rb (SimpleDelegator::__setobj__): need check for
  recursive delegation.  [ruby-core:04940]

* misc/ruby-mode.el (ruby-expr-beg): fix looking point drift.
