Zebediah Figura be541f1b0c ntdll: Add a direct futex-based implementation of condition variables.
While the current path for condition variables will ultimately use futexes if
they are available, the path for address waits is vulnerable to several
spurious wakes, which can be obviated by using condition variables as futexes
directly.

This greatly improves performance for Path of Exile.

Zebediah Figura 6060d2703c ntdll: Use a critical section to ensure that RtlWaitOnAddress compares and queues atomically.
Currently a wake may occur between calling compare_addr() and performing the
select request; in that case the thread will never be woken. Prevent this by
taking a CS around both operations.
