So far, the only way to implement periodic interval timers was to use one-shot uloop_timeout timers which are rearmed within their completion callback immediately on expiration. While simple, this approach is not very precise and interval lengths will slowly drift over time, due to callback execution overhead, scheduling granularity etc. In order to make uloop provide stable and precise interval timer capabilities, this commit introduces a new `uloop_interval` structure along with the new related `uloop_interval_set()`, `uloop_interval_cancel()` and `uloop_interval_remaining()` api functions. Periodic timers are implemented using the timerfd facility an Linux and kqueue EVFILT_TIMER events on macOS/BSD. The Lua binding has been updated to include support for the new timer type as well.
