TCP poll: TCP poll events can really only being processed when the poll from the correct device is received.

TCP timeouts: Fix some logic when there are multiple network  interfaces.  In this case, TCP timeout events can really only being processed when the poll from the correct device is received.

drivers/syslog/note_driver.c:  Add a driver that will allow an application to read buffered scheduler instrumentation data

FAT: Add an option to force all transfers to be performed indirectly through the FAT file system's internal sector buffers

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.

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.

Scheduler: Replace the boolean 'prioritized' with a uint8_t bit set so that additional attributes of a list can be specified without adding more boolean values.

sched/: Replace explict references to g_readytorun with indirect references via the this_task() macro

syslog: If syslog timestamping is enabled, don't try to get the time if the timer hardware has not yet been initialized.

Add a state variable that provides the current level of OS initialization.  This is needed by some logic that may attempt to run early in the start-up sequence, but cannot run if a sufficient level of initializaitn has not not yet occurred
