oauth: Remove expired timers from the multiplexer In a case similar to the previous commit, an expired timer can remain permanently readable if Curl does not remove the timeout itself. Since that removal isn't guaranteed to happen in real-world situations, implement drain_timer_events() to reset the timer before calling into drive_request().
Moving to drain_timer_events() happens to fix a logic bug in the previous caller of timer_expired(), which treated an error condition as if the timer were expired instead of bailing out. The previous implementation of timer_expired() gave differing results for epoll and kqueue if the timer was reset. (For epoll, a reset timer was considered to be expired, and for kqueue it was not.) This didn't previously cause problems, since timer_expired() was only called while the timer was known to be set, but both implementations now use the kqueue logic.
