Summary: Adds two flavours of generic unwinder and all the supporting cruft. If the supporting allocator is okay with bringing in sanitizer_common, they can use the fast frame-pointer based unwinder from sanitizer_common. Otherwise, we also provide the backtrace() libc-based unwinder as well. Of course, the allocator can always specify its own unwinder and unwinder-symbolizer. The slightly changed output format is exemplified in the first comment on this patch. It now better incorporates backtrace information, and displays allocation details on the second line.
