Tracking issue for Condvar::wait_timeout

[alexcrichton]

This is a tracking issue for the unstable wait_timeout feature in the standard library. An open question here is whether the tuple return value with a bool is appropriate or whether an enum of some form should be returned instead.

It now returns an opaque struct with a method that identifies if a timeout occurred.

Nominating for stabilization in the next cycle.

This issue is now entering its cycle-long FCP for stabilization in 1.5

It's likely that wait_timeout_ms won't actually be deprecated until wait_timeout hits stable.

The libs team discussed this during triage today and the decision was to stabilize.
