Backout 3f731241cb. It is a good idea, but has some unpleasant side effect... like SYSLOG and dbg() no longer work

fs/inode/, fs/vfs/, and sched/task/: File and socket descriptors are no longer allocated for kernel threads. They must use SYSLOG for output and the low-level psock interfaces for network I/O. This saves a little memory which might be important for small footprint configurations.

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().

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.

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.
