Andreas Hansson 2a675aecb9 mem: Add an internal packet queue in SimpleMemory 
This patch adds a packet queue in SimpleMemory to avoid using the
packet queue in the port (and thus have no involvement in the flow
control). The port queue was bound to 100 packets, and as the
SimpleMemory is modelling both a controller and an actual RAM, it
potentially has a large number of packets in flight. There is
currently no limit on the number of packets in the memory controller,
but this could easily be added in a follow-on patch.

As a result of the added internal storage, the functional access and
draining is updated. Some minor cleaning up and renaming has also been
done.

The memtest regression changes as a result of this patch and the stats
will be updated.
