Conrad Meyer 90a79ac576 Use time_t for intermediate values to avoid overflow in clock_ts_to_ct 
Add additionally safety and overflow checks to clock_ts_to_ct and the
BCD routines while we're here.

Perform a safety check in sys_clock_settime() first to avoid easy local
root panic, without having to propagate an error value back through
dozens of APIs currently lacking error returns.
