Adds tests for handling of Rejected, Released and Modified outcomes for
a delivery sent to a receiver. Tests show that for the Modified outcome
the broker is redelivering the message to the same receiver when the
undeliverable here value is set which violates the AMQP 1.0 specified
handling of that field. Also for Rejected outcome the broker should
be sending the rejected message to the DLQ as Rejected is supposed to
be a terminal outcome.
Small fix included to not adjust the delivery count if the Modified
outcome does not indicate that the delivery failed.
If the SASL plain mechanism arrives with the authzid value set the
mechanism needs to account for its presence and use the correct fields
of the exchange to get the username and password values. Adds some
tests to validate this fix.
Some new tests that cover some AMQP credit handling scenarios. Test
case 'testCloseBusyReceiver' currently fails due to being dispatched a
duplicate message.
Two new tests that acquire messages inside a TX and manage their
settlement and retirement in differing ways, one test works the other
'testReceiversCommitAndRollbackWithMultipleSessionsInSingleTXNoSettlement'
fails due to messages that were committed being redelivered to the
client unexpectedly.
Refactor the AMQP Message transformers both for better performance and
also to fix a number of issues with the transformers creating inbound
and outbound messages with incorrectly mapped values or extra data
appended where it should not be.
