uml: GENERIC_CLOCKEVENTS support
Enable CONFIG_GENERIC_CLOCKEVENTS.
timer_irq gets its name changed to timer_handler, and becomes the recipient of
timer signals.
The clock_event_device is set up to imitate the current ticking clock, i.e.
CLOCK_EVT_FEAT_ONESHOT is not enabled yet.
disable_timer now doesn't ignore SIGALRM and SIGVTALRM because that breaks
delay calibration.
