Stefan Brüns a5a1dca832 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.

Sebastian Held 384cfe5677 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.

Thorsten Liebig aba33c58bd excitation moved to its own extension
the benefit of this approach is, that the excitation
is subject to the extensions priorities

Thorsten Liebig 20d6547235 MPI: added cylindrical multigrid support
The cylindrical multigrid scheme needed a workaround:
An additional barrier is necessary to prevent a simultaneous MPI comm access.

Thorsten Liebig 043ef6ec4c 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
