The build system now allows incremental gem5 builds. Unfortunately,
the current solution always requires re-linking the executable.
Without the enforcement of re-linking, the fail code will be rebuilt
but not linked into gem5.

The number of cores for building gem5 is derived from /proc/cpuinfo.
As before, only the gem5.debug configuration is supported.

The checkpoint which is produced by this save method is a little bit
different to the checkpoint which is produced by the --take-checkpoint
command. It differs in the save-parameters so_state, funcExeInst, intRegs,
_upc, _nupc, _when. Tests have shown that it probably does not affect the
course of the program execution.

Encapsulated gem5-specific code into wrapper functions to separate the
build process (Fail: CMake, gem5: scons). Added some gem5-related FIXMEs.

Another CMake related FIXME added. +some cosmetics.

In fact, delete should be called in the destructor of each derived class (BochsController and Gem5Controller at the moment).

Additionally, this is the reason why ~SimulatorController is declared as virtual.

- 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.

- 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

FIXME: This shouldn't be a global variable (probably a SimulatorController
member?).  Reconsider interrupt generation being part of the generic
interface.
