This change updates several functions within libbacktrace that handle symbol information for PE/COFF and XCOFF object file formats. Instead of hardcoding the value 3 for BACKTRACE_MOREDATA_VERSION, it now uses the defined constant. This ensures consistency and makes the code more robust against future changes in the MOREDATA versioning scheme.
