* object.c (rb_str2cstr): warn if string contains \0 and length

  value is ignored.

* class.c (rb_singleton_class_clone): should copy class constant
  table as well.

* class.c (rb_include_module): sometimes cache was mistakenly left
  uncleared - based on the patch by K.Kosako.

* ruby.h: all Check_SafeStr()'s are replaced by SafeStr() to
  ensure 'to_str' be always effective.
