Add an affinity field to the attrributes to permit controlling which CPUs a pthread may run on. Implements pthread_att_setaffinity_np() and pthread_attr_getaffinity_np().

2. Move list of signal actions from the task TCB to the task group. Signal handlers are a property of the entire task group and not of individual threads in the group. I know, I preferred it the other way too but this is more compliant with POSIX.
