Check both passed args to addListener.

Place var at beginning.

By making sure the _events is always an object there is one less check
that needs to be performed by emit.

Use undefined instead of null. typeof checks are a lot faster than
isArray.

There are a few places where the this._events check cannot be removed
because it is possible for the user to call those methods after using
utils.extend to create their own EventEmitter, but before it has
actually been instantiated.

Remove unecessary splice for single listener events. Add type check for
"type" argument.

Make sure the argument passed is a string. Also use typeof === function
check instead of isArray().

Unnecessary checks were being performed on if the event existed before
being removed.

_events starts out as null, so reset to null when emptied.

Checking typeof is a lot cheaper than isArray().

setMaxListeners will now make sure a positive number is passed. Also
throwing more definitive Error types.

Small addition to ensure that exports.usingDomains is always a bool.

Ability to return just the length of listeners for a given type, using
EventEmitter.listenerCount(emitter, event). This will be a lot cheaper
than creating a copy of the listeners array just to check its length.

Slice the portion of the buffer to unshift back into the read queue

We were using a global temp file while setting the NODE_VERSION
environment variable. This resulted in simultaneous builds swapping
version numbers on occasion.

This patch removes the use of a temp file for this.

Fix #4841

This prevents fixture litter when these tests fail.

The first example uses Readable, and shows the use of
readable.unshift().  The second uses the Transform class, showing that
it's much simpler in this case.

This makes it so that `stream.push(chunk)` is the only way to signal the
end of reading, removing the confusing disparity between the
callback-style _read method, and the fact that most real-world streams
do not have a 1:1 corollation between the "please give me data" event,
and the actual arrival of a chunk of data.

It is still possible, of course, to implement a `CallbackReadable` on
top of this.  Simply provide a method like this as the callback:

    function readCallback(er, chunk) {
      if (er)
        stream.emit('error', er);
      else
        stream.push(chunk);
    }

However, *only* fs streams actually would behave in this way, so it
makes not a lot of sense to make TCP, TLS, HTTP, and all the rest have
to bend into this uncomfortable paradigm.

A primary motivation of this is to make the onread function more
inline-friendly, but also to make it more easy to explore not having
onread at all, in favor of always using push() to signal the end of
reading.

Don't emit a 'connect' event on sockets that are handed off to
net.Server 'connection' event listeners.

1. It's superfluous because the connection has already been established
   at that point.

2. The implementation is arguably wrong because the event is emitted on
   the same tick of the event loop while the rule of thumb is to always
   emit it on the next one.

This has been tried before in commit f0a440d8 but was reverted again in
ede1acc1 because the change was incomplete (at least one test hadn't
been updated).

Fixes #1047 (again).

The output of `id -G` is unreliable on OS X. It uses an undocumented
Libsystem function called getgrouplist_2() that includes some auxiliary
groups that the POSIX getgroups() function does not return.

Or rather, not always. It leads to fun bug chases where the test fails
in one terminal but not in another.

Test output is always \n and not platform dependent

Remove the errno global. It's a property on the process object now.

Fixes #3095.

Document how to run the example on the home page in more detail.

Apparently our Windows brethren are prone to double-clicking on the
binary instead of running it from the command line.

Fixes #4854.

It's cleaner to only load domain ticker logic when the domains are being
used. This makes execution slightly quicker in both cases, and simpler
from the spinner since there is no need to check if the latest callback
requires use of domains.

Not necessary, since we can handle the error properly on the first tick
now, even if there are event listeners, etc.

Additionally, this removes the unnecessary "_needTickCallback" from
startup, since Module.loadMain() will kick off a nextTick callback right
after it runs the main module.

Fix #4856

Also, exit with 128+n for signal exit n, as is The Unix Way.

Clear OpenSSL's error stack on return from Connection::HandleSSLError().
This stops stale errors from popping up later in the lifecycle of the
SSL connection where they would cause spurious failures.

This commit causes a 1-2% performance regression on `make bench-tls`.
We'll address that in follow-up commits if possible but let's ensure
correctness first.

Fixes #4771.
