Renames `options.deDupeHistory` → `options.removeHistoryDuplicates` for
`readline.createInterface(options)`.
The option name `removeHistoryDuplicates` is preferable to the
semantically identical name `deDupeHistory` because "dedupe" (short for
"deduplication") is obscure and neologistic while
`removeHistoryDuplicates` is clear, though verbose.
Updates tests and documentation for this option accordingly.

Adds `options.deDupeHistory` for `readline.createInterface(options)`. If
`options.deDupeHistory` is `true`, when a new input line being added to
the history list duplicates an older one, removes the older line from
the list. Defaults to `false`.
Many users would appreciate this option, as it is a common setting in
shells. This option certainly should not be default behavior, as it
would be problematic in applications such as the `repl`, which inherits
from the readline `Interface`.
Extends documentation to reflect this API addition.
Adds tests for when `options.deDupeHistory` is truthy, and when
`options.deDupeHistory` is falsey.

Introduced a new option `crlfDelay`. If the delay between \r and \n
exceeds `crlfDelay` milliseconds, both \r and \n will be treated as

Passing null as the output stream to readline.Interface()'s constructor

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).

Not removing 'end' listeners for input and output on the 'close' event

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`.
Make lines ending \r\n emit one 'line' event, not two (where the second
one is an empty string).
This adds a new keypress name: 'return' (as in: 'carriage return').
Fixes#3305.
While updating the readline test cases to test both "terimal: false" and
"terminal: true" mode, it turned out that the test case testing utf8 chars
being sent over multiple write() calls was failing. The solution is to use
a string_decoder instance when parsing the "keypress" events.
Before this commit, readline was inconsistent in whether or not it would emit
"line" events with or without the trailing "\n" included. When "terminal"
mode was true, then there would be no "\n", when it was false, then the "\n"
would be present. However, the trailing "\n" doesn't add much, and most of the
time people just end up stripping it manually.
Part of #4243.
