Improve coalescing of the hardclock/statclock/etc events and callout events
by specifying time where callout_process() may optionally be called, i.e.
there are some events that could be handled at that time if CPU is active,
but that also could be handled later if CPU is sleeping now. This reduces
rate of interrupts on completely idle CPU from 6-8Hz down to 4Hz as it is
in HEAD where hardclock() directly calls callout_ticka()

Reduce forced minimal interrupt rate on idle from 4Hz to 2Hz.
