Subject: [PATCH] libev: export ev_monotonic_now() and ev_monotonic_time()
ev_now()/ev_time() are affected by system time changes, which makes them
impractical for calculating timeouts. Introduce ev_monotonic_now() and
ev_monotonic_time() which work exactly as ev_now()/ev_time(), but use
monotonic clock instead of realtime.
Needed for #2527
