ci: test Python 3.6 on AppVeyor

Hey there! The failure on Travis seems like a Travis issue, but the AppVeyor one could somehow be legit.

[schlamar]

Oh yes, there is really a regression in 3.6+ (see Travis). Any idea?

[schlamar]

Please see: https://bugs.python.org/issue26685

I guess we should just remove the sock.close call?!

[schlamar]

Not sure about the UDP test case though. There is a different behavior on Linux and Windows. Is pyuv or libuv closing the underlying socket on bind error on Linux?

[schlamar]

Oh yes. libuv closes the underlying socket on bind error on Linux (https://github.com/libuv/libuv/blob/d898a1f6f87ba30e7803fe402121464553b2ffaf/src/unix/udp.c#L343) but not on Windows (https://github.com/libuv/libuv/blob/87df1448a48fb64c2b9ebe37e3344f7e5b81dd88/src/win/udp.c#L261).

Reported upstream: libuv/libuv#1336

[saghul]

Thanks for digging though it! I think the current workaround looks ok!

[schlamar]

Are you planning a new release any time soon? If not we could create a temporary branch based on the pyuv-1.3.0 tag with these changes so AppVeyor is building the Python 3.6 wheels for 1.3.0. :)

@saghul Ping :)

[schlamar]

@saghul Should I squash this in one commit? ci, test: add proper support for Python 3.6?

[schlamar]

New proposal (see commits)

[saghul]

LGTM, thanks!

BTW, setuptools has broken the Travis builds :/
