The vm module's displayErrors option attaches error arrow
messages as a hidden property. Later, core JavaScript code
can optionally decorate the error stack with the arrow message.
However, when user code catches an error, it has no way to
access the arrow message. This commit changes the behavior of
displayErrors to mean "decorate the error stack if an error
occurs."

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 does so to know the file size in advance so it doesn't have to
allocate O(n) buffers when reading the file from disk.
internalModuleReadFile() is plenty efficient though, even more so
because we want a string and not a buffer. This way we also don't
allocate a buffer that immediately gets thrown away again.

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.

`setTimeout()`, `setInterval()` and `setIntermediate` currently
throw errors when receiving non-function objects as their first
argument, but only do so when trying to execute the callback,
i.e. after the waited time has passed. This may complicate
debugging when a lot of calls to `setTimeout()`/etc. are involved,
so failing as early as possible seems like a good idea.
`setTimeout()` historically ignored an falsy first
argument, while the other functions do not and throw instead.
This patch changes this behaviour to make all three match and
adds remarks in the corresponding documentation.
