This fixes a problem in replication where RESET SLAVE could crash a running slave. mysql-test/r/rpl_failsafe.result: Added missing drop mysql-test/r/rpl_log_pos.result: Added slave stop before change master mysql-test/t/rpl_log_pos.test: Added slave stop before change master sql/sql_parse.cc: reset_slave() sends it's own errors sql/sql_repl.cc: reset_slave() sends it own error. RESET SLAVE and CHANGE MASTER will now give an error if slave is running. This fixes a problem in replication where RESET SLAVE could crash a running slave.
