Call `obj.postSend` in error case of `process.send()`. The
`net.Socket`'s handle should not be leaked.
Note that there are two callbacks invoked on handles
when they are sent to the child process over IPC pipes.
These callbacks are specified by `handleConversion` object, and
during send two of them are invoked:
* `send`
* `postSend`
Now for `net.Socket` in particular, `postSend` performs clean up by
closing the actual uv handle. However this clean up will not happen in
one of the branches. This pull request aims to fix this.

It avoids the creation of unnecessary handles. This issue is causing
intermitent failures in `test-cluster-disconnect-race` on `FreeBSD`
and `OS X`.
The problem is that the `worker2.disconnect` is being called on the
master before the `queryServer` is handled, causing the worker to
be deleted, then the Server handle is created afterwards. Later on,
when `removeWorker` is called from the `exit` handler, there are no
workers left, but one handle, thus the `AssertionError`.
Add a new `test/sequential/test-cluster-disconnect-leak` based on
`test-cluster-disconnect-race` that creates lots of workers and fails
consistently without this patch.

There is no guarantee that the `suicide` property of a worker in the
master process is going to be set when the `disconnect` and `exit`
events are emitted.
To fix it, wait for the ACK of the suicide message from the master
before disconnecting the worker. Also, there's no need to send the
suicide message from the worker if the disconnection has been
initiated in the master.
Add `test-cluster-disconnect-suicide-race` that forks a lot of workers
to consistently reproduce the issue this patch tries to solve.
Modify `test-regress-GH-3238` so it checks both the `kill` and
`disconnect` cases. Also take into account that the `disconnect` event
may be received after the `exit` event.

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.

It never sets this._consuming back to false.
ChildProcess.flushStdio() currently doesn't flush
any streams where _consuming is truthy. But, that means
that it never flushes any stream that has ever been read from.
This prevents a child process from ever closing if one of
its streams has been read from, causing issue #4049. This
commit allows consuming streams to be flushed, and the
child process to emit a close event.
