It may be desirable to make use of time warp functionality in unit tests. Separate logic from time/stop unixctl into timeval_stop() and add a new timeval_warp() interface for directing monotonic clock into slow path and advancing the current monotonic directly. This will be used in a patch that implements unit tests for the cooperative multitasking module.
