Commit 1511021 from [~tedross] in branch 'qpid/trunk'
[ https://svn.apache.org/r1511021 ]
QPID-5045 - Refactored the router data structures to support message and link
routing.
QPID-4997 - Fixed the thread safety problem.
- Wrapped "pn_delivery" in the container to allow for explicit linkage of
delivery pairs.
- Removed the linkage between "message" and "delivery". Messages can now be
discarded as
soon as the last copy is delivered because their status will be tracked in
the dx_delivery
object.
- Removed tx_handler from the set of callbacks in the container. There is no
need for this
notification (sendable delivery) because Dispatch does not create outbound
deliveries
until it is ready to send them (i.e. deliveries are created and advanced in
one synchronous
operation).
- Replaced the out_fifo of messages per outbound-link with a pair of fifos
(one for messages
and one for state changes) per link. Note that even inbound-links need to
send state
changes outbound. This change addresses QPID-4997.

>
> Dispatch router supports two flavors of routing:
> - Message Routing is performed using the "to" field and uses linked delivery
> records to track disposition and settlement.
> - Link Routing is performed using the target/source of an attach frame and
> creates "virtual circuits" of linked-links to carry messages across a network.
> This Jira tracks changes to the router data structures to support these
> routing features.
