This saves one byte per Query_log_event on disk compared to 5.0.[0..3]. Compatibility problems with 5.0.x where x<4 are explained in the comments in log_event.cc. Putting back s/my_open(O_TRUNC)/(my_delete+my_create) change which had been wiped away by somebody doing a wrong 4.1->5.0 merge (which happened just before 5.0.3 :( ). Applying it to new events for LOAD DATA INFILE. If slave fails in Execute_load_query_log_event::exec_event(), don't delete the file (so that it's re-usable at next START SLAVE). And (youpi!) fix for BUG#3247 "a partially completed LOAD DATA INFILE is not executed at all on the slave" (storing an Execute_load_query_log_event to binlog, with its error code, instead of Delete_file_log_event).
