HTTP/2: expose function to push single resource to modules.

This makes it possible for 3rd party modules to implement alternative
methods for deciding which resources to push to clients on a per-request
basis (e.g. by parsing HTML from the response body, by using a custom
Link header parser, ...).

No functional changes.
