[riot-notifications] [RIOT] posix: add pthread wrapper (#219)

I started to make the wrapper a bit more compatible to msba2. I found several required adjustments:
1. There is no (more) define for `_POSIX_THREAD_THREADS_MAX` so i readded it to `pthread.h`
2. the useful types have to be activated in `pthread.h`
3. free and malloc cannot be found until `oneway_malloc.h` is included and an underscore is put in front of the functios. This applies for `sched.c` and `pthread.c` (maybe i just missed something here)

anyway, the absence of `__sync_bool_compare_and_swap` still prevents to compile for msba2  
I think the implementation of http://armv6-atomic.googlecode.com/files/armv6_atomic.h is a very good way of implementation, although encapsulated in c++.  
On the basis that we need the pointers to the swapped, a pure asm implementation could be difficult as we only can access/swap registers (Im not very familiar with asm, so please correct me if this is bullshit). 
I think we should add a c function similar to the exemplary code in a separate `atomic.h`
