The latest version of DRAMSys required several API changes which were
applied in this commit.
Also, the README for the usage of DRAMSys has been updated.
The updated version fixes a bug in DRAMSys that caused some full-system
simulations to loop endlessly.
GitHub Issue: https://github.com/gem5/gem5/issues/1452
This commit contains the rest of the base 2 vs base 10 cache/memory
size clarifications. It also changes the warning message to use
warn(). With these changes, the warning message should now no
longer show up during a fresh compilation of gem5.

Recent breaking changes in the DRAMSys API require user code to be
updated. These updates have been applied to the gem5 integration.
Furthermore, as DRAMSys started to use CMake dependency management,
it is no longer sensible to maintain two separate build systems for
DRAMSys. The use of the DRAMSys integration in gem5 will therefore
from now on require that CMake is installed on the target machine.
Additionally, support for snapshots have been implemented into DRAMSys
and coupled with gem5's checkpointing API.
Add DRAMSys as a new AbstractMemorySystem to the gem5 stdlib.
Also, provide convenient subclasses with predefined DRAMSys
configurations.
Add two new stdlib examples:
- dramsys-traffic.py: Demonstrates the usage of DRAMSys
using the stdlib TrafficGenerators
- arm-hello-dramsys.py: A variant of the arm-hello.py
script that uses DRAMSys as it's memory.
These DRAMSys memory components are only compiled into the standard
library if DRAMSys is not compiled into gem5.
