lib/timer: Add current_time_now() function for immediate timestamp
Add a current_time_now() function which gets an immediate monotonic timestamp instead of using the cached value from the event loop. This is useful for callers that need precise times, such as the Babel RTT measurement code. Signed-off-by: Toke Høiland-Jørgensen <toke@toke.dk>
