Previously, the map printing in tombstones for 64 bit devices uses a variable length value. This means that the maps are not lined up. The new format is to print the map as 00000000'00000000 in all ways. Also fix a bug where the backtrace_map_t did not initialize all parameters. Add unit tests for all of the dump_all_maps function.
