All minidump objects now own their all of their children, rather than having them maintain weak pointers and requiring callers to maintain ownership. The only weak object in the entire tree now is the “extra memory” added to a MinidumpMemoryListWriter by its AddExtraMemory() method. Extra memory aliases objects owned elsewhere in the tree, typically by a MinidumpThreadWriter as stack memory. Non-“extra” memory added to a MinidumpMemoryListWriter by its AddMemory() method is strongly owned. Many objects are now deleted through base pointers, and in those cases, the base classes now have public virtual destructors. The ultimate base, MinidumpWritable, is still protected to guard against direct instantiation and deletion, and thus its destructor does not need to be virtual. This updates mini_chromium to eeb3b6a4f020 specifically for that revision, which includes necessary updates to scoped_ptr. It also picks up: eeb3b6a4f020 Update base/move.h and base/memory/scoped_ptr.h to match 67ad2efafaba More porting to Windows be27a006421e AUTHORS: Fix link post-git migration flag day. 05f5b1503230 Add codereview.settings to mini_chromium. a32c2b199811 Beginnings of Windows support in mini_chromium TEST=minidump_test R=rsesek@chromium.org Review URL: https://codereview.chromium.org/674153002
