-  Disables binary logging for one thread, and resets it back to what it was
-  before being disabled. 
-  Some functions (like the internal mysql_create_table() when it's called by
-  mysql_alter_table()) must NOT write to the binlog (binlogging is done at the
-  at a later stage of the command already, and must be, for locking reasons);
-  so we internally disable it temporarily by creating the Disable_binlog
-  object and reset the state by destroying the object (don't forget that! or
-  write code so that the object gets automatically destroyed when leaving a
-  block, see example in sql_table.cc).
