stdlib: Improving synthetic traffic generation.

Browse Source 
This change adds a new traffic generator module to the standard
library that can read a .cfg file describing the traffic pattern
as a state machine. It wraps around the TrafficGen SimObject.
In addition it adds a method to ComplexGenerator to set the
traffic from outside using python generators like the example
found in configs/dram/sweep.py.
