Calling SHOW BINLOG EVENTS FROM <offset> with an invalid offset writes error messages into the server log about invalid reads. The read errors that occur from this command should only be relayed back to the user though, and not written into the server log. This is because they are read-only and have no impact on server operation, and the client only need be informed to correct the parameter. This patch fixes this by omitting binary log read errors from the server when the invocation happens from SHOW BINLOG EVENTS. Additionally, redundant error messages are omitted when calling the string based read_log_event from the IO_Cache based read_log_event, as the later already will report the error of the former.
