This patch is adding support for generating memory requests which set
the StreamID/SubstreamID field, so that is possible to emulate devices
attached to an external IOMMU/SMMU with a Traffic generator.

The traffic generator currently assumes that it is always driven from
a configuration file. Split it into a base class (BaseTrafficGen) that
handles basic packet generation and a derived class that implements
the config handling (TrafficGen).
