OS X has a tiny 1kb hard-coded buffer size for stdout / stderr to
TTYs (terminals). Output larger than that causes chunking, which ends
up having some (very small but existent) delay past the first chunk.
That causes two problems:
1. When output is written to stdout and stderr at similar times, the
two can become mixed together (interleaved). This is especially
problematic when using control characters, such as \r. With
interleaving, chunked output will often have lines or characters erased
unintentionally, or in the wrong spots, leading to broken output.
CLI apps often extensively use such characters for things such as
progress bars.
2. Output can be lost if the process is exited before chunked writes
are finished flushing. This usually happens in applications that use
`process.exit()`, which isn't infrequent.
See https://github.com/nodejs/node/issues/6980 for more info.
This became an issue as result of the Libuv 1.9.0 upgrade. A fix to
an unrelated issue broke a hack previously required for the OS X
implementation. This resulted in an unexpected behavior change in node.
The 1.9.0 upgrade was done in c3cec1eefc,
which was included in v6.0.0.

The tty.ReadStream constructor initializes this as a socket,
which causes a read to be initiated. Even though during stdin
initalization we call readStop shortly after, the read operation
can consume keypress events from the system buffers.

Some files in `lib` were using `require` to load modules that were
subsequently not used in the file. This removes those `require`
statements.

Changes included in this commit are
1. Making the deprecation messages consistent. The messages will be in
the following format
x is deprecated. Use y instead.
If there is no alternative for `x`, then the ` Use y instead.` part
will not be there in the message.
2. All the internal deprecation messages are printed with the prefix
`(node) `, except when the `--trace-deprecation` flag is set.

Many of the util.is*() methods used to check data types
simply compare against a single value or the result of
typeof. This commit replaces calls to these methods with
equivalent checks. This commit does not touch calls to the
more complex methods (isRegExp(), isDate(), etc.).

The copyright and license notice is already in the LICENSE file. There
is no justifiable reason to also require that it be included in every
file, since the individual files are not individually distributed except
as part of the entire package.
Turn on strict mode for the files in the lib/ directory. It helps
catch bugs and can have a positive effect on performance.

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().
It seems like a good idea on the face of it, but lowWaterMarks are
actually not useful, and in practice should always be set to zero.
It would be worthwhile for writers if we actually did some kind of
writev() type of thing, but actually this just delays calling write()
and the overhead of doing a bunch of Buffer copies is not worth the
slight benefit of calling write() fewer times.
Technically saying `tty.ReadStream#setRawMode()` is correct,
but since a typical use cannot instantiate `tty.ReadStream` themselves,
and 99% of the time the only instance is `process.stdin`,
then a little clarification seemed necessary.
The overall goal here is to make readline more interoperable with other node
Streams like say a net.Socket instance, in "terminal" mode.
See #2922 for all the details.
Closes #2922.
This makes it so that the stdin TTY-wrap stream gets ref'ed on
.resume() and unref'ed on .pause()
The semantics of the names "pause" and "resume" are a bit weird, but the
important thing is that this corrects an API change from 0.4 -> 0.6
which made it impossible to read from stdin multiple times, without
knowing when it might end up being closed. If no one has it open, this
lets the process die naturally.
