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).

/*
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
function...).
