`context.rs` enhancements
...
* Improve the phrasing of some docstrings and comments
* Add warning comments about attempts to validate memory addresses
at reader/writer instantiation time
* Create the `reader_writer` method for ergonomically instantiate
a reader/writer pair covering the same memory region. This method
is also slightly more efficient than calling `reader` and `writer`
separately
* Clean up `check_vaddr` for clarity and rename it to `check_vaddr_lowerbound`
for explicity
* Include the data length check before calling `check_vaddr_lowerbound`
in `atomic_load` and `atomic_fetch_update` for further consistency
with the delayed buffer validation

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.
