pep-484: asyncio

in this patch the asyncio/events.py module, which
existed only to raise errors when trying to attach event
listeners, is removed, as we were already coding an asyncio-specific
workaround in upstream Pool / Session to raise this error,
just moved the error out to the target and did the same thing
for Engine.

We also add an async_sessionmaker class.  The initial rationale
here is because sessionmaker() is hardcoded to Session subclasses,
and there's not a way to get the use case of
sessionmaker(class_=AsyncSession) to type correctly without changing
the sessionmaker() symbol itself to be a function and not a class,
which gets too complicated for what this is. Additionally,
_SessionClassMethods has only three methods on it, one of which
is not usable with asyncio (close_all()), the others
not generally used from the session class.
