Fix for prepared statements: added setting of 'neg' in Item_param::set_time() (looks like the only forgotten member). It's the second place I find where 'neg' was forgotten. The symptom was unexpected negative times in the binary log when running tests/client_test.c (test_date() in fact): # at 43009 #040210 15:46:42 server id 1  log_pos 43009     Query   thread_id=1     exec_time=0     error_code=0 SET TIMESTAMP=1076424402; INSERT INTO test_date VALUES('2000-01-10 11:16:20','-11:16:20' etc
