This patch adds a first version of a script that processes the debug
output and generates a command trace for DRAMPower. This is work in
progress and is intended as a snapshot of ongoing work at this point.
The longer term plan is to link in DRAMPower as a library and have one
instance of the model per rank, and instantiate it based on a struct
passed from gem5. Each command will then be a call to the model and no
parsing of traces will be necessary.
