wdog.h does not contain any application interface, only internal OS interface. Further, it is non-standard. Move wdog.h from include/ to include/nuttx. For the same reason, move the description of the watchdog timer interfaces from the Users Guide to the Porting Guide.

If we run out of pre-allocated watchdog times, the logic will allocate additional timers from the heap. A reserve of pre-allocated watchdog timers is maintained so that there will always be timers available for interrupt handlers.

When reading the system timer, don't read a struct timespec, convert it to a fake tick count, then back to a timespec. Remove CLOCK_ACTIVETIME.. it is non-standard, unused, and gets in the way of changes like this

Tickless Stuff: Back out the risky timer operations when the ready-to-run list is modified. That is unsafe. An ugly workaround is just to keep an interval timer going all of the time with a minimum duration equal to the timeslice interval.

Change all time conversions. Yech. New timer units in microseconds breaks all existing logic that used milliseconds in the conversions. Something likely got broken doing this, probably because I confused a MSEC2TICK conversion with a TICK2MSEC conversion. Also, the tickless OS no appears fully functional and passes the OS test on the simulator with no errors

Change CONFIG_MSEC_PER_TICK to CONFIG_USEC_PER_TICK. This gives more options for system timers in general, but more importantly, let's us realize higher resolution for the case of CONFIG_SCHED_TICKLESS=y -- of course, at the risk of some new interger overvflow problems
