doc: remove note about close event
test: disable simple/test-process-getgroups on os x

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.
deps: upgrade libuv to 2a8d2a5
net: omit superfluous 'connect' event

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 f0a440d but was reverted again in
ede1acc because the change was incomplete (at least one test hadn't
been updated).

Fixes #1047 (again).
stream: Break up the onread function

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.
stream: Add stream.unshift(chunk)
stream: There is no _read cb, there is only push

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.
doc: Provide 2 examples of SimpleProtocol parser

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.
build: windows should append date if nightly
http: use socket.once, not socket.on

Register the 'close' event listener with .once(), not .on().

It doesn't matter in the grand scheme of things because the listener
doesn't keep references to any heavy-weight objects but using .once()
for a oneshot listener is something of a best practice.
test: Put fs write test files in tmp

This prevents fixture litter when these tests fail.

Merge branch 'v0.9.11-release'
Now working on 0.9.12
doc: Correct version in changelog
blog: Post about v0.9.11
build/windows: don't use wrong version number

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.
