TIMER: Timing corrections and enhancements

Browse Source 
- Add support to query remaining usecs on pending events.
- Generalized the sim_interval adjustment in sim_idle to allow more than
   a single decrement.
- More overhead reduction when idling.
- Carry usec values as double through out to fully support long wall clock
   delays.
