process: invoke EventEmitter on `process`

This properly sets the `_maxListeners` property, which
fixes the max listener warning. Closes #4924.
bench: Add flag to be silent in runner

This is helpful in tracking down bailouts and deopts in Stream classes,
without triggering one from the string write in console.log
stream: Split Writable logic into small functions

1. Get rid of unnecessary 'finishing' flag
2. Dont check both ending and ended. Extraneous.

Also: Remove extraneous 'finishing' flag, and don't check both 'ending'
and 'ended', since checking just 'ending' is sufficient.
stream: Remove output function from _transform

Just use stream.push(outputChunk) instead.
stream: _write takes an encoding argument

This vastly reduces the overhead of decodeStrings:false streams,
such as net and http.
stream: Use class for write buffer entries
build: define nightly tag external to build system
process: invoke EventEmitter on `process`

This properly sets the `_maxListeners` property, which
fixes the max listener warning. Closes #4924.
child_process: handle ENOENT correctly on Windows
cares: Set process._errno, not global.errno

This makes test-internet pass
DNS: Support NAPTR queries

They were previously removed in a90bc78534d94940a6b726c01cf8427c296b4c63.
src: remove unused symbols in node_file.cc
handle_wrap: replace unref_ field with flags_ field

Prep work for a follow-up commit that adds support for close callbacks.
handle_wrap: add close callback support
net: use close callback, not process.nextTick

Don't emit the 'close' event with process.nextTick.

Closing a handle is an operation that usually *but not always* completes
on the next tick of the event loop, hence using process.nextTick is not
reliable.

Use a proper handle close callback and emit the 'close' event from
inside the callback.

Update tests that depend on the intricacies of the old model.

Fixes #3459.
http: fix multiple timeout events

Fixed up slightly by @isaacs so as not to miss 'timeout' events in some
cases.
node: Add --throw-deprecation

Extremely handy when tracking down a flood of recursive nextTick warnings.
test: Pass cli flags in pummel/test-regress-GH-892
stream: Remove unnecessary nextTick usage in Writable

Fix #4928
stream: Increase highWaterMark on large reads

If the consumer of a Readable is asking for N bytes, and N > hwm,
then clearly we have set the hwm to low, and ought to increase it.

Fix #4931
