* 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]

* hash.c (env_aset): do not treat nil as key-removing value.
  [ruby-list:40865]

* parse.y (method_call): allow aref expression ([]) to take a
  block.

* parse.y (block_dup_check): a function to check duplication of
  a block argument and an actual block.

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

* lib/cgi.rb: add underscore aliases CGI::escape_html,
  CGI::unescape_html, CGI::escape_element, CGI::unescape_element.
  [ruby-core:05058]
