* error.c (exc_exception): clone the receiver exception instead of

  creating brand new exception object of the receiver.

* eval.c (rb_eval_string_wrap): extend new ruby_top_self, not
  original self.

* eval.c (rb_eval_cmd): respect ruby_wrapper if set.

* eval.c (eval): do not update ruby_class unless scope is not
  provided.

* eval.c (eval): preserve wrapper information.

* eval.c (proc_invoke): ditto.

* eval.c (block_pass): ditto.

* parse.y (void_expr): too much warnings for void context
  (e.g. foo[1] that can be mere Proc call).

* error.c (rb_name_error): new function to raise NameError with
  name attribute set.

* eval.c (rb_f_missing): set name and args in the exception
  object. [new]

* error.c (name_name): NameError#name - new method.

* error.c (nometh_args): NoMethodError#args - new method.

* lex.c (rb_reserved_word): lex_state after tRESCUE should be
  EXPR_MID.

* gc.c (add_heap): allocation size of the heap unit is doubled for
  each allocation.

* dir.c (isdelim): space, tab, and newline are no longer
  delimiters for glob patterns.

* eval.c (svalue_to_avalue): new conversion scheme between single
  value and array values.

* eval.c (avalue_to_svalue): ditto.

* eval.c (rb_eval): REXPAND now uses avalue_to_svalue(), return
  and yield too.

* eval.c (rb_yield_0): use avalue_to_svalue().

* eval.c (proc_invoke): Proc#call gives avaules, whereas
  Proc#yield gives mvalues.

* eval.c (bmcall): convert given value (svalue) to avalue.
