MEDIUM: freq_ctr: replace the per-second counters with the generic ones

It remains cumbersome to preserve two versions of the freq counters and
two different internal clocks just for this. In addition, the savings
from using two different mechanisms are not that important as the only
saving is a divide that is replaced by a multiply, but now thanks to
the freq_ctr_total() unificaiton the code could also be simplified to
optimize it in case of constants.

This patch turns all non-period freq_ctr functions to static inlines
which call the period-based ones with a period of 1 second. A direct
benefit is that a single internal clock is now needed for any counter
and that they now all rely on ticks.

These 1-second counters are essentially used to report request rates
and to enforce a connection rate limitation in listeners. It was
verified that these continue to work like before.
