sql/log_event.cc:
  - cleanup_load_tmpdir() did not work at all because it forgot to indicate
  the directory part of the path when calling my_delete().
  - A misplaced R_POS_OFFSET (fortunately this was no bug as this constant is 0).
sql/sql_repl.cc:
  - fix fake_rotate_event() for pos>4G (correction of a change I pushed yesterday).
