* parse.y (str_extend): should check nesting parentheses in #{}.

* process.c (pst_wstopsig): returns nil unless WIFSTOPPED() is
  non-zero.

* process.c (pst_wtermsig): returns nil unless WIFSIGNALED() is
  non-zero.

* process.c (pst_wexitstatus): returns nil unless WIFEXITED() is
  non-zero.

* eval.c (rb_thread_select): tv_sec and tv_usec should not be
  negative.

* signal.c (posix_signal): do not set SA_RESTART for SIGVTALRM.

* parse.y (call_args2): block_arg may follow the first argument in
  call_args2.

* eval.c (stack_check): should avoid stack length check during
  raising SystemStackError exception.
