hi,
adding support to report error from event string parsing.
This patchset contains support for standard parsing errors
and more logic to recognize tracepoint and 'pmu//' terms,
like:
$ perf record -e 'sched:krava' ls
invalid or unsupported event: 'sched:krava'
\___ unknown tracepoint
$ ./perf record -e 'cpu/even=0x1/' ls
invalid or unsupported event: 'cpu/even=0x1/'
\___ unknown term
$ perf record -e cycles,cache-mises ls
invalid or unsupported event: '..es,cache-mises'
\___ parser error
any feedback about the error string shape would be great ;-)
Changes are also reachable in here:

perf/event_parse_error
thanks
