feature merge bs-coreoptimize->trunk: Atomic Operations, Threading, Spinlock implemnetation. [commit 1/2, windows will followup]

- Added Abstractions for Atomic Operations (lock instructions.. windows guy's may now this as Interlocked* stuff ..)
- Added Threading api abstraction for Pthread based OS's and Windows
- Added Spinlock Implementation (uses CAS / if you need more informations - just read the source - its simple.)

- Due to Interlocked(Compare)Exchange64 .. we now require at least i686 (Pentium Pro) for 32Bit Builds :)
	youll also may feel some performance improvements when using 32bit builsd due to "newer" minimal arch
	the compiler is now able to use CMOV's ....


================================================================
= Important Warning: 
================================================================
Dont use threading at the moment athena is not threadsafe!
you'll mess up everthing when accessing data from other threads .., no synchronization is provided.

A way to process tasks asynchronously will come up after / with the new socket system.
