Remove special handling when asserting on a pair of arguments objects.
The code being removed will only run if both `expected` and `actual` are
arguments objects. Given that situation, the subsequent code for
handling everything else works just fine.
Tests added to confirm expected behavior.
This came about while trying to improve test coverage. The segment of
code removed had no test coverage. I was unable to write a test that
would both exercise the code and fail if the code was removed. Further
examination indicated that this was because the special handling was not
needed.

When `useGlobal` is false, tab completion in the repl does not enumerate
global properties. Instead of just setting these properties blindly on
the global context, e.g.
context[prop] = global[prop]
Use `Object.defineProperty` and the property descriptor found on
`global` for the new property in `context`.
Also addresses a previously unnoticed issue where `console` is writable
when `useGlobal` is false.
If the binary has been built with `./configure --without-intl` then the

This uses a watchdog thread to wait for SIGINT and generally works

- Adds a method to the existing timer-based watchdog to check if it
stopped regularly or by running into the timeout. This is used to
tell a SIGINT abort from a timer-based one.
- Adds (internal) `process._{start,stop}SigintWatchdog` methods to
start/stop the watchdog thread used by the above option manually.
This will be used in the REPL to set up SIGINT handling before

Guard against the call to write() inside pipe's ondata pushing more data

This is fine but results in awaitDrain being increased more than once.
The problem with that is when the destination does drain, only a single

Reset the `readableState.awaitDrain` counter after manual calls to
`.resume()`.
What might happen otherwise is that a slow consumer at the end of the
pipe could end up stalling the piping in the following scenario:
1. The writable stream indicates that its buffer is full.
2. This leads the readable stream to `pause()` and increase its
`awaitDrain` counter, which will be decreased by the writable’s next
`drain` event.
3. Something calls `.resume()` manually.
4. The readable continues to pipe to the writable, but once again
the writable stream indicates that the buffer is full.
5. The `awaitDrain` counter is thus increased again, but since it has
now been increased twice for a single piping destination, the next
`drain` event will not be able to reset `awaitDrain` to zero.
6. The pipe is stalled and no data is passed along anymore.
The solution in this commit is to reset the `awaitDrain` counter to
zero when `resume()` is called.

Improves performance of allocating unsafe buffers, creating buffers from
an existing ArrayBuffer and creating .slice(...) from existing Buffer by
avoiding deoptimizing change of prototype after Uint8Array allocation
in favor of ES6 native subclassing.
This is done through an internal ES6 class that extends Uint8Array and
is used for allocations, but the regular Buffer function is exposed, so
calling Buffer(...) with or without `new` continues to work as usual
and prototype chains are also preserved.
Performance wins for .slice are +120% (2.2x), and, consequently, for
unsafe allocations up to +95% (1.9x) for small buffers, and for safe
allocations (zero-filled) up to +30% (1.3x).

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
