Fix several timing problems:

Browse Source 
* suspend-until-time was broken (CPU would be suspended and never resumed)
 * timer devices would fire an initial callback even if not set up with a time yet
 * triggers requested after a time would fire twice; once right away and once at the target time

Fixes many regressions.
