`HandleWrap::OnClose` destroys the underlying C++ object and null's the
internal field pointer to it. Therefore there should be no references to
the wrapping JavaScript object.
`null` the process' `_channel` field right after closing it, to ensure
no crashes will happen.

Previously, in _validateStdio we were using stdio.fd || stdio. If
stdio.fd was falsy (or 0 in the case of stdin), then the entire stdio
object would be passed which could cause a crash.

Add an optional callback parameter to `ChildProcess.prototype.send()`
that is invoked when the message has been sent.
Juggle the control channel's reference count so that in-flight messages
keep the event loop (and therefore the process) alive until they have
been sent.
`ChildProcess.prototype.send()` and `process.send()` used to operate
synchronously but became asynchronous in commit libuv/libuv@393c1c5
("unix: set non-block mode in uv_{pipe,tcp,udp}_open"), which landed
in io.js in commit 07bd05b ("deps: update libuv to 1.2.1").

This commit better handles calls to process.binding() in lib/ by
no longer lazy loading the bindings (the load times themselves are
rather miniscule compared to the load time of V8) and never reloading
the bindings (which is 172 times slower than referencing a variable with
the same value).

Many of the util.is*() methods used to check data types
simply compare against a single value or the result of

equivalent checks. This commit does not touch calls to the

Currently child_process.exec() assumes that cmd.exe is on the PATH,
and fails with a spawn ENOENT error if it is not.
The Windows 'comspec' environment variable contains the full filepath
to the default command interpreter, eg "C:\Windows\System32\cmd.exe".
Should it not be set, we fall-back to using 'cmd.exe' from PATH, as
before.

Fix possible deadlock, when handles are sent in both direction
simultaneously. In such rare cases, both sides may queue their
`NODE_HANDLE_ACK` replies and wait for them.
fix#7465
When sending a socket to a child process via IPC pipe,
`child_process.js` picks a raw UV handle from `_handle` property, sends
it, and assigns `null` to the property. Sending the same socket twice
was resulting in a runtime error, since we weren't handling the empty
`_handle` case.
In case of `null` `_handle` we should send just a plain text message
as passed it was passed to `.send()` and ignore the handle, letting
users handle such cases themselves instead of throwing the error at
runtime.
fix#5469
This implements the user-facing APIs that lets one run a child process
and block until it exits.
Logic shared with the async counterpart of each function was refactored
to enable code reuse.
Docs and tests are included.
Spawn's arguments were documented to be optional, as they are for the
other similar child_process APIs, but the code was missing. Result was
`child_process.spawn('node', {})` errored when calling slice() on an
Object, now it behaves as the documentation said it would.
1. Swallow errors when sending internal NODE_HANDLE_ACK messages, so
they don't crash the process.
2. Queue process.disconnect() if there are any pending queued messages.
Fixes test-child-process-fork-net2.js on win.
After the uv upgrade, uv_spawn will now fail faster for certain
failures like ENOENT. However, our tests and other people may be
depending on that error being passed to the callback instead of a
throw.
There's no need to create a new Buffer instance if we're just going to
immediately call toString() at the end anyway. Better to create a
string up front, and setEncoding() on the streams, and do a string
concatenation instead.
Libuv now returns errors directly. Make everything in src/ and lib/
follow suit.
The changes to lib/ are not strictly necessary but they remove the need
for the abominations that are process._errno and node::SetErrno().
