Namhyung Kim 2f197b9d7e tools lib traceevent: Introduce pevent_strerror
The pevent_strerror() sets @buf to a string that describes the
(libtraceevent-specific) error condition that is passed via @errnum.

This is similar to strerror_r() and does same thing if @errnum has a
standard errno value.

To sync error string with its code, define PEVENT_ERRORS with _PE()
macro and use it as suggested by Steven.
