Add support for Intel PT call_return events and itrace options to the perf Python extension so standalone Python scripts can decode and inspect low-level instruction traces. Specifically: - Add a call_return callback parameter and itrace option string to perf.session, treating explicit None (Py_None) callbacks as omitted. - Expose the perf.call_return object with db_id, parent_id, insn_count, cyc_count, comm, pid, tid, call_time, return_time, branch_count, call_ref, return_ref, flags, and call_path (resolved as a perf.callchain ordered from outermost caller to callee, populating frame->map and frame->sym so call_path entries expose resolved symbol and DSO names). - Export perf.CALL_RETURN_NO_CALL, perf.CALL_RETURN_NO_RETURN, and perf.CALL_RETURN_NON_CALL flag constants. - Expose session.e_machine and session.is_64_bit properties, preferring recorded thread ELF machines (perf_session__e_machine) over perf_env so pipe-mode traces do not prematurely cache host bitness. - Support optional vmlinux, kallsyms, and symfs symbol configuration parameters (and PERF_SYMBOL_VMLINUX, PERF_SYMBOL_KALLSYMS, PERF_SYMBOL_SYMFS environment fallbacks) in perf.session, resetting symbol_conf pointers and freeing vm_tm_corr_args, cpu_bitmap, and ptime_range in pyrf_session__delete().
