Backporting a changeset made for 5.0. Comments from there: The fix refines the algorithm of generating DROPs for binlog. Temp tables with common pseudo_thread_id are clustered into one query. Consequently one replication event per pseudo_thread_id is generated. mysql-test/r/rpl_temporary.result: results changed mysql-test/t/rpl_temporary.test: test to generate problematic drop in binlog to feed it to restarting slave to see no stop. sql/sql_base.cc: change in drop temprorary tables alg in close_temporary_tables.
