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

[Namhyung Kim <namhyung@kernel.org>]

Hi,

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.

Thanks,
Namhyung
