Build and test with Cython 0.26

Disable auto-pickling to work around https://github.com/cython/cython/issues/1786. We don't want to allow that in a point-release of gevent anyway.

Defer adjusting the stdlib's list of active threads until threading is monkey-patched

Previously this was done when :mod:`gevent.threading` was imported.
That module is documented to be used as a helper for monkey patching,
so this should generally functionally be the same, but some
applications ignore the directly import that module anyway.

A positive consequence is that ``import gevent.threading, threading;
threading.current_thread()`` will no longer return a DummyThread
before monkey-patching. Another positive consequence is that PyPy will
no longer print a ``KeyError`` on exit if :mod:`gevent.threading` was
imported *without* monkey-patching.

Fixes #984.

Use a weak reference to clean up the link for local objects if they die before the greenlet does (#983)

If libev is not embedded, we still want to set GEVENT_NO_CFFI_BUILD=1 to
prevent setup.py from trying to configure libev, regardless whether cffi
modules will actually be built or not.

Commit 59581a8a "Add python 3.5
selectors test, and remove the devpoll selector under 3.5. also update
the monkey documentation." Introduced a regression by moving the exec of
scripts into a main() function. If the script being run with exec has
import statements those are now locally scoped to the main() function
which can break the script.

It does not appear that this local scoping was intentional so the fix is
to exec the script in the global scope, returning the previous behavior.
This also requires setting __package__ = None otherwise the script
appears to be run in the gevent __package__
