    Subject[RFC PATCHSET 0/3] tools lib traceevent: Generic error handling for pevent

    This is a small patch series for preparation of the die removal.
    I added some error code to be used for pevent_parse_event() and
    _strerror function much like the perf target does.

    I don't like the name 'pevent' but since it's a part of the API
    so I used it for the name.

    This can eliminate a few of die() and do_warning() but will lose
    some details on the error message - i.e. event name. I couldn't
    think of a way that doesn't lose such info after returning from
    the function. But I guess we might get the info from the context.

    Patch 01 is independent and can be applied separately.

    Any comments are welcome.
