a3cafbd78b Revisited breakpoint implementation of gem5.
Now, the gem5 implementation equals the Bochs variant. Note that its
necessary to enable CONFIG_EVENTS_BREAKPOINTS_RANGE in order to use
range breakpoints.
In addition, gem5 distinguishes between macro- and microops. With the
new implemenation, onBreakpoint is only called when a macroop changes.

9c62e4a7f2 - Added signaling of trap situations needed in the weather-monitor to gem5.
- Fixed setting of instruction address for simulator.onMemoryAccess() calls.

afca00ce0a - Added a define which marks the use of BPRangeListener
- Gem5 now has two different implementation for breakpoints.
  - If only BPSingleListener are used, gem5 Breakpoints are used
  - If BPRangeListener are used, gem5 calls onBreakpoint() in every simulated instruction

b052c0494b Architecture changes (only gem5 implementation right now):
- The register manager is gone. It's functionality is now encapsulated in the
  CPU classes.
- For the client, there is the ConcreteCPU class that encapsulates the access
  to the CPU state (including registers) and architecture details. The
  correspondig objects for the CPUs inside the simulator can be accessed
  through the SimulatorController.getCPU() function.
- Listener got a new ConcreteCPU* member to filter for which CPU the events
  should fire. The default NULL is used as wildcard for all aviable CPUs. The
  events respectively got a ConcreteCPU* member to indicate which CPU really
  fired the event.
- For the server, there is CPUArchitecture to access the architecture details.

e0e95faa5b 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
