Emit two line events when there is a delay between
CR('\r') and LF('\n').
Introduced a new option `crlfDelay`. If the delay between \r and \n
exceeds `crlfDelay` milliseconds, both \r and \n will be treated as
separate end-of-line input. Default to 100 milliseconds.
`crlfDelay` will be coerced to [100, 2000] range.

x is deprecated. Use y instead.
If there is no alternative for `x`, then the ` Use y instead.` part

this creates a new internal module responsible for providing
the repl created via "iojs" or "iojs -i," and adds the following
options to the readline and repl subsystems:
* "repl mode" - determine whether a repl is strict mode, sloppy mode,
or auto-detect mode.
* historySize - determine the maximum number of lines a repl will store
as history.
The built-in repl gains persistent history support when the
NODE_REPL_HISTORY_FILE environment variable is set. This functionality
is not exposed to userland repl instances.

There was an underlying assumption in readline.emitKeypressEvents (and
by extension emitKey) that the given stream (usually process.stdin)
would emit 'data' once per keypress, which is not always the case.
This commit buffers the input stream and ensures a 'keypress' event is
triggered for every keypress (including escape codes).

If an input stream would emit `end` event, like
`fs.createReadStream`, then readline need to get the last line
correctly even though that line isnt ended with `\n`.
On windows, libuv will immediately make a `ReadConsole` call (in the
thread pool) when a 'flowing' `uv_tty_t` handle is switched to
line-buffered mode. That causes an immediate issue for some users,
since libuv can't cancel the `ReadConsole` operation on Windows 8 /
Server 2012 and up if the program switches back to raw mode later.
But even if this will be fixed in libuv at some point, it's better to
avoid the overhead of starting work in the thread pool and immediately
cancelling it afther that.
See also f34f1e3, where the same change is made for the opposite
flow, e.g. move `resume()` after `_setRawMode(true)`.
