Using Date.now() introduces problems when operating under load or
otherwise with constrained resources. Use Timer.now() to mitigate.
The problem was identified in `test-readline-interface` where under
heavy load, `\r` and `\n` were received so far apart that they were
treated as separate line endings rather than a single line ending.
Switching to `Timer.now()` prevented this from happening.

Line 486 and 525 contain for loops where a length property is cached in
a variable (for example, itemLen). This used to be a performance
optimization, but current V8 handles the optimization internally.
These caching variables are removed, and the length property is used
directly instead.

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.

Rather than the pseudo-wcwidth impl used currently, use the ICU
character properties database to calculate string width and
determine if a character is full width or not. This allows the
algorithm to correctly identify emoji's as full width, ensures
the algorithm will continue to fucntion properly as new unicode
codepoints are added, and it's faster.
This was originally part of a proposal to add a new unicode module,
but has been split out.
