Included in this change: - Change the tag when a pointer is freed so it's easy to detect if an already freed pointer is being used. - Move the free backtrace out of the header. This backtrace is only used under only some circumstances, so no need to allocate space in all headers for it. - Add new option free_track_backtrace_num_frames to specify how many frames to record when the free occurs. This removes the dependency on the backtrace option to get backtraces. Bug: 26739265 Change-Id: I76f5209507dcf46af67ada162a7cb2bf282116f2
