Update uvloop to 0.12.1

[pyup-bot]

This PR updates uvloop from 0.11.3 to 0.12.1.

Changelog

0.12.0

New Features

* New SSL implementation. The new implementation is faster and
and more complete, and will become the default SSL implementation
in asyncio 3.8.  This is a significant change that warrants a release
candidate to make sure it is tested properly.

See the linked issue for more details.

* New `uvloop.install()` helper function.

Instead of

python
import asyncio
import uvloop
asyncio.set_event_loop_policy(uvloop.EventLoopPolicy())


it is now possible to simply write

python
import uvloop
uvloop.install()

Bug Fixes

* All bug fixes from `0.11.0`—`0.11.3` are included in

the `Protocol.connection_lost()` anyways.
(by fantix in 848e4785 for 195, 199)

* Don't use non-existent `UDPTransport._address` attribute.
