This commit adds a public channel property to ChildProcess. The
existing _channel property is aliased to the new property, with
the intention of deprecating and removing it in the future.

There's an issue on some `OS X` versions when passing fd's between processes.
When the handle associated to a specific file descriptor is closed by the sender
process before it's received in the destination, the handle is indeed closed
while it should remain opened. In order to fix this behaviour, don't close the
handle until the `NODE_HANDLE_ACK` is received by the sender.
Added `test-child-process-pass-fd` that is basically `test-cluster-net-send` but
creating lots of workers, so the issue reproduces on `OS X` consistently.

Currently, if an IPC event handler throws an error, it can

The require('constants') module is currently undocumented and mashes

This commit prevents child process stdio streams from being
automatically flushed on child process exit/close if a 'readable'
event handler has been attached at the time of exit.
Without this, child process stdio data can be lost if the process
exits quickly and a `read()` (e.g. from a 'readable' handler)
hasn't had the chance to get called yet.

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.

When a client calls read() with a nonzero argument
on a Socket, that Socket sets this._consuming to true.
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.
