global_event_loop: return running loop for current thread

Like asyncio.get_event_loop(), return the running loop for the
current thread if there is one, and otherwise construct a new
one if needed. This allows the _safe_loop function to become
synonymous with the global_event_loop function.

For the case of "loop running in non-main thread" of API
consumer, this change makes portage compatible with PEP
492 coroutines with async and await syntax. Portage
internals can safely begin using async / await syntax instead
of compat_coroutine.
