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)

Fixes #981

In a comment. [skip ci]

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.
