Wrap _DEX_TypeList to _DEX_TypeList_align before append to list. - Fix the issue described by map_verify_error_test(). - When inject a _DEX_ClassDef, dexfile_insert_classdefs_relative() should also inject related _DEX_TypeList. - But, dex_append_obj_list() does not known that _DEX_TypeList should be wrapped to to _DEX_TypeList_align and appended to DEXFile.typeLists. We add a special case in dex_append_obj_list() to wrap _DEX_TypeList before trying to insert to a list.
