        with pthread_cond::TimedWait().
        (check_valid_pointer): Change definiton to void const *.
        (verifyable_object_isvalid): Add new parameter to allow identification of
        static initializers, and return a enum rather than magic numbers.

        (__pthread_cond_dowait): New function, contains core logic from
        __pthread_cond_wait and __pthread_cond_timedwait. Decrement (*cond)->waiting
        before reentering the cond access mutex to allow detection of lost signals.
        (__pthread_cond_timedwait): Rename to pthread_cond_timedwait, and call
        __pthread_cond_dowait after calculating the wait length.
        (__pthread_cond_wait): Rename to pthread_cond_wait, and call
        __pthread_cond_dowait.
