This patch adds support for reading input traces encoded using
protobuf according to what is done in the CommMonitor.
A follow-up patch adds a Python script that can be used to convert the
previously used ASCII traces to protobuf equivalents. The appropriate
regression input is updated as part of this patch.
This patch changes the traffic generator period such that it does not
completely saturate the DRAM controller and create an ever-growing
backlog in the queued port.
A separate patch updates the stats.
This patch adds a basic regression for the traffic generator. The
regression also serves as an example of the file formats used. More
complex regressions that make use of a DRAM controller model will
follow shortly.
