Restructured the gem5 backend:

- FailGem5Device is gone.
- There are now changes directly made to the gem5 source.
- Gem5Connector is a helper class that is compiled inside the gem5 context to workaround problems with gem5 header in fail.

Things that are working:
- BPSingleListener
- MemAccessListener
- Save and restore simulator state
