      Fix for BUG#4971 "CREATE TABLE ... TYPE=HEAP SELECT ... stops slave (wrong DELETE in binlog)":
      replacing the no_log argument of mysql_create_table() by some safer method
      (temporarily setting OPTION_BIN_LOG to 0) which guarantees that even the automatic
      DELETE FROM heap_table does not get into the binlog when a not-yet-existing HEAP table
      is opened by mysql_create_table().
      
      
      mysql-test/r/rpl_heap.result:
        result update
      mysql-test/t/rpl_heap.test:
        changing test to test a bug (but anyway, mysql-test-run --manager looks like not working in 4.1 currently,
        so this test is never run).
      sql/log.cc:
        new class Disable_binlog used to temporarily disable binlogging for one thread.
      sql/mysql_priv.h:
        removing argument no_log from mysql_create_table(); no_log was not perfect as some
        binlogging could still be done by open_unireg_entry() for a HEAP table.
      sql/sql_class.h:
        new class Disable_binlog used to temporarily disable binlogging for one thread.
      sql/sql_parse.cc:
        removing no_log arg from mysql_create_table()
      sql/sql_table.cc:
        removing no_log from mysql_create_table(); instead using new class Disable_binlog.
        Disabling binlogging in some cases, where the binlogging is done later by some other code
        (case of CREATE SELECT and ALTER).

      Fix for BUG#2477 "Slave stop with error after master reboot if use HEAP tables": · e7a90646
      unknown authored
      when we open the HEAP table for the first time since server restart,
      in hp_open(), we set a flag to propagate this info to the handler level
      which then writes a DELETE FROM this_heap_table to the binlog.
      It is not a perfect solution for the bug, because between the server start and 
      the first open of the table, the slave still had old data in his table so
      a SELECT on the slave may show wrong content. But if there is a --init-file
      to populate the HEAP table on master as startup, then this is a safe fix
      (I'll put a note about init-file in the HEAP section of the manual).
      
      
      heap/hp_info.c:
        new info variable implicit_emptied
      heap/hp_open.c:
        If this is the first open of the HEAP table, it means it is empty,
        so we mark it.
      include/heap.h:
        new variables implicit_emptied
        (we need one in HEAPINFO for the hp_info() call).
      sql/ha_heap.cc:
        report info to upper level
      sql/handler.h:
        new info 'implicit_emptied' in the handler level; only HEAP uses it.
      sql/sql_base.cc:
        When a HEAP table is opened for the first time, write a DELETE FROM to the binlog,
        for replication and mysqlbinlog|mysql.
        Monty: I added the
        entry->file->implicit_emptied= 0;
