There are many subclasses of the Memory class and the overwhelming majority of them don't need to be exposed externally. We move all of them to internal headers except MemoryOfflineBuffer, which moves to a separate header. This dramatically reduces the exposed API surface and makes the code more modular. Also, remove the Offline code from libbacktrace. It's not used any where. Test: Unit tests pass, clean tree still builds Change-Id: I55dacdf080daba0bfe65c1ad53a4b326bb482e83
