Query the page table item reference
...
This commit adds a page table item reference type at the `PageTableConfig`
trait. Therefore it allows `Cursor::query` to return a reference to the
mapped item, reducing copies.
Also, it removes the `Iterator` implementation of the `Cursor` since the
yielded item cannot be a reference type.

Make `wake_robust_futex` atomic
...
Replace `VmWriter::atomic_update` with `VmWriter::atomic_compare_exchange`,
which takes the old value for comparison and new value instead of a
closure to compute it. This version has one less unsafe call.
Then use `atomic_compare_exchange` to reimplement the looping logic
of `wake_robust_futex` and make it atomic.
