Here is a new patch:

* Clarified some recent instances of “coroutine” as “native coroutine” (term taken from PEP 492)
* Put “coroutine” before “coroutine function” in the glossary.
* Merge “Use as coroutines” section into new coroutine compound statement documentation
* Add links to glossary entry
* Added one mention of the new “async” coroutines to “asyncio”. I understand this is meant to be supported in 3.5, but still needs more documentation work.
