perf trace: Add Perl scripting support
Implement trace_scripting_ops to make Perl a supported perf trace scripting language. Additionally adds code that allows Perl trace scripts to access the 'flag' and 'symbolic' (__print_flags(), __print_symbolic()) field information parsed from the trace format files. Also adds the Perl implementation of the generate_script() trace_scripting_op, which creates a ready-to-run perf trace Perl script based on existing trace data. Scripts generated by this implementation print out all the fields for each event mentioned in perf.data (and will detect and generate the proper scripting code for 'flag' and 'symbolic' fields), and will additionally generate handlers for the special 'trace_unhandled', 'trace_begin' and 'trace_end' handlers. Script authors can simply remove the printing code to implement their own custom event handling.
