Provide a callout_hash() private function which is equivalent to the
get_bucket() one except than performing the division for the number of
buckets in the wheel. Inline the two aforementioned functions in order
to avoid the overhead due to function call.

Optimize the callout_tick() code. Right now it scans the entire wheel
only when it's needed (i.e. we wrapped around all the wheel). Otherwise
it scans only the buckets from the last examined in previous scan to the
one relative to present time.
