Improve the broker's handling of message corruption (#2136) (#2143)
This commit improves the brokers handling of messages that are corrupt
and can't be read, such as unmarshaling the properties or body.
Currently if there is an error an IOException is triggered and can lead
to a client connection be closed. Furthermore for queues messages can be
stuck and no new messages can be delivered.
To improve things the following changes have been made:
* The MarshallingSupport utility that is used to unmarshal message
properties and bodies has improve validation to check for errors
such is incorrectly encoded size values.
* The broker will now handle message format errors both when messages
are evaluated to add to subscriptions and during dispatch to consumers
when the messages are already on a subscription.
* The Stomp protocol converter was fixed to not auto ack or track acks
until the message has been converted.
* AMQP no longer swallows message format errors and will throw so the
erors can be handled by the TransportConnection.
All of these changes allow the broker to deal with corrupt messages and
remove them (and possibly DLQ) vs causing the connections to close or
the messages to block consumers forever in the queue case.
(cherry picked from commit b20e61c7ef736a04ad07a934ea8de628550c6cf2)
