Add protections around 32 and 64 bits code. The 32 bits is not really usefull but I want to have both of them similar. Anyway, some architectures does not provide 64 bits atomic operations, so they will never get compiled. Let's just hope nobody use them ...
...
- remove all unsigned from the */atomic.h files
- export defines depending on the architecture

Update the atomic stuff. Not all architectures provide the "fastest" atomic one. The only required atomic
...
operations are actually the compare_and_set 32 and 64 bits. For all others atomic there is a fallback in sys/atomic.c
For ia32 I add a workaround the ebx register. When compiling with -fPIC ebx is reserved for the shared object interface (store some global pointer). On the same time cmpxchg8b use ebx and ecx to store the new value. The workaround save the ebx content before cmpxchg8b and restore it afterward. There is still a possible bug !!! If we get interrupted between the push and pop of the ebx then we will definitivelly crash ...
