Guard xmmintrin.h include so it is only used when necessary
...
The x86/SSE specific code for Flush-To-Zero is only used when
SSE_CORRECT_DENORMALS is not defined. Guarding the include allows the
code to compile on e.g. ARM.

bugfix Windows: FTZ and DAZ bits in SSE computation unit is thread dependent.
...
This fix sets the FTZ ans DAZ bits in every thread to gain the speedup.
Linux seems to store these bits per process rather than per thread.

MPI: added cylindrical multigrid support
...
The cylindrical multigrid scheme needed a workaround:
An additional barrier is necessary to prevent a simultaneous MPI comm access.

extensions: multithreading support added

every extension can either implement the single threaded methods e.g. DoPreVoltageUpdates()
or the multithreading aquivalent method e.g. DoPreVoltageUpdates(int threadID)
Engine_Ext_UPML class is an example for a multithreading extensions
