46756821c4
This includes removing the map_info.c source and replacing it with the BacktraceMap class to handle all map related code. Change all callers of libbacktrace map functionality. Also modify the corkscrew thread code so that it doesn't need to build the map twice (once in the corkscrew format and once in the libbacktrace format).
