Add a CPU affinity set to the TCB if SMP is enable and use this CPU set as a mask for determining which CPUs the thread may run on. 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().

Rename cpuset_t to cpu_set_t which is the type used in some non-standard Linux/GNU interfaces. Move definitions of cpu_set_t to include/sys/types.h. Add prototypes for sched_setaffinity(), sched_getaffinity(), pthread_attr_setaffinity_np(), pthread_attr_getaffinity_np(), pthread_setaffinity_np(), and pthread_getaffinity_np(). No implementation is yet in place.

1. SMP: Fix an assertion. SMP-specific change accidentally made in non-SMP code
...
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.
