LOAD DATA INFILE is now replicated properly, except for cleanup on

Browse Source 
Stop event and bugs the test suite could not catch
Did some big restructuring of binlog event classes - most important
change is that now each event class has exec_event method and one does
not need to modify slave core code to add a new event. Slave code is
now much smaller and easier to read



include/my_sys.h:
  pre_code and arg in IO_CACHE
mysql-test/r/rpl_log.result:
  updated result for LOAD DATA INFILE fix
mysys/mf_iocache.c:
  pre_close routine and arg pointer for callback magic
sql/log.cc:
  changed MYSQL_LOG so that write() method is for generic
  Log_event - removed redundant code
sql/log_event.cc:
  added classes for file events
  added exec_event() method to all classes
  restructured/cleaned up event classes
sql/log_event.h:
  added classes for file events
  added exec_event() method to all classes
  restructured/cleaned up event classes
sql/mf_iocache.cc:
  pre_close/arg
sql/mysqld.cc:
  added slave-load-tmpdir and old-rpl-compat options
sql/slave.cc:
  changed exec_event() to use Log_event::exec_event()
  some routines are now needed in log_event.cc and cannot be static/inline
  general cleanup
sql/slave.h:
  some routines are now extern because they are called from log_event.cc
sql/sql_class.cc:
  added slave_net
sql/sql_class.h:
  added slave_net to THD
  MYSQL_LOG::write now handles generic Log_event
sql/sql_load.cc:
  changes for new handling of LOAD DATA INFILE replication
sql/sql_repl.cc:
  added log_loaded_block() callback for IO_CACHE
sql/sql_repl.h:
  added structure to pass args to IO_CACHE callback from mysql_load
