Improve rate limiting
If we have pending IO, we should commit it before going to sleep,
not just wait for IO that has already been issued.
Also improve the delay functions to return the time spent, so
that users don't have to track tha separately if they care about
the precision.

Unify the time handling
Some options are in seconds, if no units are given. These include
runtime/timeout, startdelay, and ramp_time. Handle this
appropriately. Internally it should all be microseconds now, it's
just the conversion factor.

fio: allow milliseconds on all time specifiers

Add ramp_time option
Sometimes it's useful to let a job settle for a little while
before taking any measurements on latency and throughput, since
the initial rate on eg a write workload may be much higher than
the longer sustained rate.
So add a ramp_time option that allows the user to specify a lead
ramp time that must have passed before fio takes any performance
numbers into account.
