Travis is reporting src/gevent/test__* as uncovered, for some reason, but I don't get that locally.

Need to use an editable install on appveyor to find our test files; should probably loosen that restriction for downstream [skip travis]

In preperation for its removal.

Fixes #1305.

Write modified module source to a tempfile so we get correct tracebacks.

See https://ci.appveyor.com/project/denik/gevent/builds/20122331/job/9uowlkm47ayqwkxx#L1800

Find greenlets in Cython code, keeping the GIL.

Mostly (hopefully) fixes #1302

Drop `sudo` from our Travis config, following current recommendation

[appveyor skip]

[skip appveyor]
