Subject:  Big wallclock/stopwatch refactor. It was long overdue.

 * --enable-clock and --enable-monotonic are gone
 * tain_sysclock() has been renamed tain_wallclock_read()
 * tain_wallclock_read() reads from CLOCK_REALTIME (or gettimeofday())
 * tain_clockmon[_init]() have been renamed to tain_stopwatch_[read|init]()
and now accept a monotonic clock name as an extra argument
 * tain_now() points to the system (wall) clock by default
 * tain_now_set_[stopwatch|wallclock]() can be used to switch

 Now to make a pass on all skarnet.org programs and add a
tain_now_set_stopwatch() call everywhere needed... >.>
