socket.destroy() triggers a 'close' event from the socket which triggers
the onClose handler of HTTPAgent which calls self.removeSocket(). So by
calling self.removeSocket() prior to socket.destroy() we end up with two
calls to self.removeSocket().
If there are pending requests, removeSocket ends up creating a new socket.
So if there are pending requests, each time a request completes, we tear
down one socket and create two more. So the total number of sockets grows
exponentially and without regard for any maxSockets settings. This was
noticed in https://github.com/nodejs/node/issues/4050. Let's get rid of
the extra calls to removeSocket so we only call it once per completed
request.

The `events` module already exports `EventEmitter` constructor function
So, we don't have to use `events.EventEmitter` to access it.

Between `ClientRequest` and `Agent`. The circular require was doing
weird things at load time, like making the `globalAgent` property
be `undefined` from within the context of the "_http_client"
module.
Removing the circular dependency completely fixes this.
This commit effectively removes the undocumented `Agent#request()`
and `Agent#get()` functions.
Otherwise the string triggers an assertion error in node_http_parser.c,
line 370:
assert(Buffer::HasInstance(args[0]) == true);
because the first argument is not a Buffer object.
The `options` that were being passed in before here are specific to a
single request, which kinda defeats the purpose of using an Agent in the
first place.
On a worse note, these `options` have not yet been "processed" by the
`http.ClientRequest` class, so if `port: null` is set (like it is as the
result of a `url.parse()` call), then they take preference over the
processed values since the agent's "options" get mixed in last in the
`createSocket()` function.
Fixes#6197.
Fixes#6199.
Closes#6231.
There are some agent subclasses using this today.
Despite the addRequest function being undocumented internal API, it's
easy enough to just support the old signature for backwards
compatibility.
Instead of destroying sockets when there are no pending requests, put
them in a freeSockets list, and unref() them so that they do not keep
the event loop open.
Also, set the default max sockets to Infinity, to prevent the awful
surprising deadlocks that happen when more connections are made.
