try authenticating with bad credentials, and you'll get a hang until php times out. This is because amqp does not specify how to handle a failed authentication, and servers tend to just close the connection. php-amqplib doesn't consider that possibility. A patch to fix is attached. You don't get an error that indicates auth failure (well, how can you really?) but at least you don't have the php process hang until the 30 second timeout is hit.

Actually, remove the check for timed_out. That breaks consumers. For the authentication failure, you only need to check for eof and break out of the loop.

Lyolik please review these bugs.
