bug#11763265 Potential bug with new --raw mode with mysqlbinlog
There were two reported artifacts on possible operations with uninitialized Log_event* pointer
But only a case of pre-4.0 load-data LOAD_EVENT in --raw mode appears to be problematic.
Load_log_event *le= (Load_log_event*)ev
has ev==NULL in that case.
whereas Rotate event is indeed handled correctly.
Fixed by enforcing all events incl LOAD_EVENT to be dumped as it's
supposed to be in the raw mode without reformating the events into load-date event
types of the latest binlog format.
CREATE_FILE_EVENT is eliminated from the load-data-needs-conversion check which is rather
sources code cleaup as checking was ineffective in that case anyway.
In case not raw_mode LOAD_EVENT of the 3.23 server version require conversion into the current load-data formats. In case of raw_mode all events including LOAD_EVENT do not need any extra treatment.

If this is a Rotate event, maybe it's the end of the requested binlog;
