BUG#6883: Added tests for create/drop temporary table, UNLOCK TABLES

If a create table can not do implicit commit, the stmt now fails
CREATE/DROP TEMPORARY TABLE is now flushed to binlog


mysql-test/include/rpl_stmt_seq.inc:
  Documentation, cleared up code
mysql-test/r/rpl_ddl.result:
  New results
mysql-test/t/rpl_ddl.test:
  Added tests for create/drop temporary table
  Added tests for different types of locks in UNLOCK TABLES
  Cleared up code/documentation
sql/sql_parse.cc:
  If A CREATE TABLE fails to do implicit commit, then the stmt now fails (DROP works in same way)
  CREATE/DROP TEMOPORARY TABLE is now flushed to binlog
