2015-01-16	Rewrite Condvar::wait_timeout and make it public	Steven Fackler	-0/+50
	The implementation is a direct adaptation of libcxx's condition_variable implementation. pthread_cond_timedwait uses the non-monotonic system clock. It's possible to change the clock to a monotonic via pthread_cond_attr, but this is incompatible with static initialization. To deal with this, we calculate the timeout using the system clock, and maintain a separate record of the start and end times with a monotonic clock to be used for calculation of the return value.
