rate_limit_is_ready()

static int rate_limit_is_ready ( ratelim_t * lim, time_t now )

static

If the rate-limiter lim is ready at now, return the number of calls to rate_limit_is_ready (including this one!) since the last time rate_limit_is_ready returned nonzero. Otherwise return 0. If the call number hits RATELIM_TOOMANY limit, drop a warning about this event and stop counting.
