* Use typed ioctl calls
* Make enumerate() return an iterator instead of a vec
* Fix(?) events() behavior
* read() into a buf of mem::MaybeUninit
* Add Device.wait_ready()
* impl AsRawFd for Device
* Add remaining ioctls
* Make Key a simple u32 code for future-proofing
* Move MAX for bitflags into associated constants; fix Display, tweak compensation logic
* derive Debug for Device, move constants into constants.rs
* Add docstrings and seatbelts to eviocgbit and eviocgabs
* Increase formality per #243
* Make Device optional fields Option, address unclear naming
* Fix warnings and remove unsafe code
* Eliminate duplicate structs already in libc; fix incorrect eviocgbit lengths, remove transmute
* Avoid hiding unsafe behind macros; use File rather than libc::open
* Change signatures of eviocgbit and eviocgabs to take slices; use align_to_mut to more safely cast slices
* Replace do_ioctl_buf! with wrapper fn
* Add a sanity check for align_to_mut
* Fix incorrect slice casts, add debug asserts for sanity
* Bump revision
