Small-and-safe fix for bug #218: "LOAD DATA INFILE IGNORE is well

logged, but read as LOAD DATA INFILE REPLACE"
This was just bad && instead of &, but nasty consequences.
This should be merged to 4.0 BUT it will not be automatic (some code
has moved from log_event.h to log_event.cc, and log_event.cc has changed);
please Merging Man, do 'bk grep REPLACE_FLAG' in 4.0/sql
to find all the new places.
