This makes the famous `EventEmitter memory leak` warnings occurring
when the listener count for a given event exceeds a specified number
more programatically accessible, by giving them properties referring
to the event emitter instance and the event itself.
This can be useful for debugging the origins of such a warning when
the stack itself doesn’t reveal enough information about the event
emitter instance itself, e.g. when manual inspection of the
already-registered listeners is expected to be useful.

Use blockquotes instead of code blocks for stability markers in
the docs. Doing that:
- Makes the makers appear correctly when viewed e.g. on github.
- Allows remark-lint rules like `no-undefined-references` to work
properly (https://github.com/nodejs/node/pull/7729).

Addresses #5566. The `ee.once()` function is currently documented as
invoking the listener, and then removing it when the event is
triggered. However, this is not really the case. The listener is removed
and _then_ invoked. This only matters in a narrow set of use cases, but
when it matters, it matters that the docs are correct.
See the issue (#5566) for a discussion on why the code has not been
modified to match the documentation, but instead the documentation has
been modified to match the code.

A handful of modules (including readable-streams) make
inappropriate use of the internal _events property. One
such use is to prepend an event listener to the front
of the array of listeners.
This adds EE.prototype.prependListener() and
EE.prototype.prependOnceListener() methods to add handlers
to the *front* of the listener array.
Doc update and test case is included.
