Implementation of the Delay Queue, an extra delay for all memory transactions in the memory controller.

Hi Shawn. I've committed it. Sorry for the inconvenience.

HI Shavvn, Are you testing with traces? We implemented the Delay Queue (DQ) as part of this integration with a CPU simulator. So it is only visible right now from the DRAMSim2 perspective if the libdramsim is used. Moreover, if DQ_DEPTH is not present in the sys config file, a value of 0 is considered and the logic is the same as without the patch. But if is present, DQ comes to place when the actual_update() function is called. We designed it like this to avoid noise with the current DRAMSim2 users. This way, they can still use the simulator without the effects of the DQ.
