AMQP: Multiple Sends within an OB Channel Adapter

Browse Source 
In preparation for: https://github.com/spring-cloud/spring-cloud-stream-binder-rabbit/issues/209

When `multiSend` is true and multiple messages are sent as the payload
of a message, each message is sent within the `invoke()` method of the
`RabbitTemplate`.

* Fix javadoc typo

* Fix DSL Spec hierarchy

* Protected CTOR/fields in new and modified specs

* Protected CTORs, fields for remaining AMQP Specs

Requires a `RabbitTemplate`.
When `wait-for-confirms` is true, `RabbitTemplate.waitForConfirmsOrDie()` is invoked after the messages have been sent.
With a transactional template, the sends will be performed in either a new transaction or one that has already been started (if present).
