Subject: [PATCH 20/24] tools list traceevent: Change pevent_parse_event to return event format
Changing pevent_parse_event to return 'struct event_format',
for the parsed event if the return pointer is specified.
This way we can remove pevent_parse_format which does the
same stuff just without 'struct pevent' object. We will
need this change in following patches.
