mysqlbinlog segfaults if --position is just before Exec_load event
mysqlbinlog prints uncommented warnings if --database and compiled with debug
mysqlbinlog --database does not filter LOAD DATA INFILE


client/mysqlbinlog.cc:
  * Don't stop in Append_block when there is no Create_file. Just print a warning.
  * Test LOAD DATA (Create_file) against --database.
  * Don't print "no skip" when you don't skip an event when using --database (it
  causes syntax errors in 'mysql').
  * Print a warning in Exec_load if there is no Create_file.
