Minimal amount of changes to make EventListener a heap-allocated type
again. The existence of the EventListener implies that it is already
listening; accordingly the new() and listen() methods on EventListener
have been removed.
cc #104

This is a breaking change. It makes `new()` take no parameters in its
signature and `listen()` take a reference to an event in its signature.
This should avoid a footgun where a listener can be waited on without
listening on it.

The EventListener for the upcoming libstd-based implementation needs to
be pinned, so this commit sets up the infrastructure for the pinned
EventListener.
This is a breaking change.
