Merge #222

222: Transfer gpio-cdev repo ownership to embedded Linux team r=japaric a=posborne

Currently hosted at https://github.com/posborne/rust-gpio-cdev.  The repo would be migrated to rust-embedded/gpio-cdev.

[`gpio-cdev`](https://crates.io/crates/gpio-cdev) is a new crate for interacting with GPIOs in Linux using the character device API (the sysfs interface is now deprecated and will be going away in future kernels [2020]).  Differences from the old API are [covered in the project README](https://github.com/posborne/rust-gpio-cdev#sysfs-gpio-vs-gpio-character-device).  Now that the initial work for the crate is done and an initial version of this crate, I want to transfer ownership over to the working group.

I didn't see a documented process for this kind of transfer, so I'm winging it a bit and using the change to the team ownership as a review checkpoint for the overall inclusion decision.  In this case, several (but not all) of the changes from the [Post Transfer TODO List](https://github.com/rust-embedded/wg/blob/master/ops/post-transfer.md) have already been done on the repo.  The other would be done once moved over -- several of the other Linux repos which have been around for awhile need a refresh along the same lines (many of those date back to when I created this GH org a few years back).

r? @rust-embedded/embedded-linux 

---

Since this crate is very new (0.1 was just published today), review and feedback on the APIs is, of course, greatly appreciated.
