Subject [jira] [Commented] (QPID-3252) Regression: broker no longer explicitly flushes messages to store on execution.sync or when sync command bit set.

Summary
-------

Broker now issues an explicit flush for each received message that has the sync flag set in
the message.transfer command.
Broker also tracks all messages received that do _not_ have the sync flag set, and will flush
these messages on receipt of an execution.sync.


This addresses bug QPID-3252.

> In the previous release of the broker, an execution.sync command, or a message.transfer
command with a sync flag would cause the broker to explicitly flush the message(s) and pend
until the flushes complete.  In the new asynchronous model, the broker does not initiate a
flush under these scenarios.  Without explicitly flushing, the completion of a message.transfer/execution.sync
may delay for an unacceptable amount of time (ex. 1sec+) when used with store.
