Subject: WL#3023 (Use locks in a statement-like manner):   Table maps are now
 written on aquiring locks to tables and released   at the end of each logical

  Disabling cleanup code
mysql-test/r/binlog_row_blackhole.result:
  Result change
mysql-test/r/binlog_row_mix_innodb_myisam.result:
  Result change
mysql-test/r/binlog_stm_ctype_cp932.result:
  Result change
mysql-test/r/rpl_row_charset.result:
  Result change
mysql-test/r/rpl_row_create_table.result:
  Result change
mysql-test/t/rpl_row_create_table.test:
  Binlog position change
sql/handler.cc:
  Writing table map after external_lock()
sql/handler.h:
  Adding class for table operation hooks.
sql/log.cc:
  Adding binlog_write_table_map() to THD.
  Removing write_table_map() from MYSQL_LOG.
sql/log.h:
  Minor interface changes to move table map writing.
sql/log_event.cc:
  Removing pre-allocation of memory for buffers.
  Allowing ULONG_MAX as table id denoting an event to ignore (only used to transfer flags).
  Adding code to collect tables while seeing table maps and lock collected tables
  when seeing a binrow event.
  Debriding code as a result of the above changes.
sql/log_event.h:
  Minor interface changes.
sql/mysql_priv.h:
  Adding hooks argument to create_table_from_items().
sql/parse_file.cc:
  Minor fix to avoid crash in debug printout.
sql/rpl_rli.h:
  Adding list of tables to lock to RLI structure.
sql/slave.cc:
  Using list of tables to lock from RLI structure.
sql/sql_acl.cc:
  Removing redundant pending events flush.
sql/sql_base.cc:
  Moving pending event flush.
  Using flag to guard to clear statement transaction only if this is the original
  open tables state.
sql/sql_class.cc:
  Adding flag for open tables state.
  Removing redundant pending events flushes.
  Write a dummy event to indicate that the tables to lock should be emptied
  on the slave.
sql/sql_class.h:
  Adding open tables state flags.
  Adding binlog_write_table_map() function to THD.
  Changes to select_create() to support new locking scheme.
sql/sql_insert.cc:
  Adding rollback of statement transaction on error. It can now contain
  events after locking tables.
sql/sql_load.cc:
  Removing redundant pending event flush.
sql/sql_table.cc:
  Adding hooks argument to create_table_from_items().
  Calling prelock hook before starting to lock tables.
