test: update cwd-enoent tests for AIX

On AIX you can not remove a directory that you are currently inside of
as it results in an EBUSY error. "EBUSY: resource busy or locked".
Updated the tests accordingly so that they are skipped on AIX.

PR-URL: https://github.com/nodejs/node/pull/2889

2015-09-17, Version 4.1.0 (Stable) Release

Notable changes:

* buffer:
  - Buffers are now created in JavaScript, rather than C++. This increases the speed of buffer creation (Trevor Norris) https://github.com/nodejs/node/pull/2866.
  - `Buffer#slice()` now uses `Uint8Array#subarray()` internally, increasing `slice()` performance (Karl Skomski) https://github.com/nodejs/node/pull/2777.
* fs:
  - `fs.utimes()` now properly converts numeric strings, `NaN`, and `Infinity` (Yazhong Liu) https://github.com/nodejs/node/pull/2387.
  - `fs.WriteStream` now implements `_writev`, allowing for super-fast bulk writes (Ron Korving) https://github.com/nodejs/node/pull/2167.
* http: Fixed an issue with certain `write()` sizes causing errors when using `http.request()` (Fedor Indutny) https://github.com/nodejs/node/pull/2824.
* npm: Upgrade to version 2.14.3, see https://github.com/npm/npm/releases/tag/v2.14.3 for more details (Kat Marchán) https://github.com/nodejs/node/pull/2822.
* src: V8 cpu profiling no longer erroneously shows idle time (Oleksandr Chekhovskyi) https://github.com/nodejs/node/pull/2324.
* v8: Lateral upgrade to 4.5.103.33 from 4.5.103.30, contains minor fixes (Ali Ijaz Sheikh) https://github.com/nodejs/node/pull/2870.
  - This fixes a previously known bug where some computed object shorthand properties did not work correctly (https://github.com/nodejs/node/issues/2507).

buffer: construct Uint8Array in JS

Overall construction time of Typed Arrays is faster in JS, but the
problem with using it normally is zero-fill of memory. Get around this
by using a flag in the ArrayBuffer::Allocator to trigger when memory
should or shouldn't be zero-filled.

Remove Buffer::Create() as it is no longer called.

The creation of the Uint8Array() was done at each callsite because at

tsc: adjust TSC membership for IBM+StrongLoop

Following the IBM+StrongLoop announcement last week, we
(@piscisaureus, @bnoordhuis, @srl295, @mhdawson, and myself)
want to take a moment to reiterate our personal commitment
to Node.js and the Foundation.

Per the TSC rules, any one company is limited to no more than
1/4 of the voting seats on the TSC and after talking it over
amongst ourselves, @srl295 and @mhdawson have elected to step
back from the TSC for now.

What I would propose is that they continue to participate in the
weekly TSC meetings as observers; and that once the membership
expands, they be considered once again for full TSC status.

Both Steven and Michael will continue to be actively involved
with Node.js. Both are active members of various Working Groups.
(Michael chairs the Benchmarking workgroup and Steven chairs the
Intl workgroup.)

Per the discussion on #2471, the JS symbols checked for by this test
were occasionally too deep in the stack and were being ignored by the
tick processor.

I have addressed this by increasing the stack depth inspected by the
tick processor and looking for the eval symbol which is more likely
to be present. Additional flakiness was caused by occasional misses
of the code creation event for the JS function being executed. I now
have separate code snippets to test for JS and C++ symbols and if
the code creation event is missed for the JS symbol test then I check
for a percentage of UNKNOWN symbols in processed output. This is
considered a success as the processing scripts in the node repository
are still correctly processing the ticks recieved from the v8
scripts. Further investigation is needed into the v8 profiling
scripts to determine why code creation events are being missed.

deps: cherry-pick 6da51b4 from v8's upstream

Original commit message:

    TypedArray accessor detection: consider entire prototype chain

    When looking up a special accessor for known TypedArray fields
    ("length", "byteLength", "byteOffset"), consider the entire
    prototype chain, not only the direct prototype.
    This allows subclasses of TypedArrays to benefit from fast
    specialized accesses.

    Review URL: https://codereview.chromium.org/1313493005

    Cr-Commit-Position: refs/heads/master@{#30678}

Improvement depends on the code, but generally brings us back to the

crypto: replace rwlocks with simple mutexes

It was pointed out by Zhou Ran that the Windows XP implementation of
uv_rwlock_rdlock() and friends may unlock the inner write mutex on a
different thread than the one that locked it, resulting in undefined
behavior.

The only place that uses rwlocks is the crypto module.  Make that use
normal (simple) mutexes instead.

OpenSSL's critical sections are generally very short, with exclusive
access outnumbering shared access by a factor of three or more, so
it's not as if using rwlocks gives a decisive performance advantage.

test: refactor to eliminate flaky test

This retains the key elements of test-child-process-fork-getconnections
(forks a child process, sends a bunch of sockets, uses getConnections()
to enumerate them) but contains some code to work around an apparent
intermittent bug that occurs on OS X where a socket seems to close
itself unexpectedly.

https://github.com/nodejs/node/issues/2610 was opened for the bug that
was causing the problem in the first place.

child_process: add callback parameter to .send()

Add an optional callback parameter to `ChildProcess.prototype.send()`
that is invoked when the message has been sent.

Juggle the control channel's reference count so that in-flight messages
keep the event loop (and therefore the process) alive until they have
been sent.

`ChildProcess.prototype.send()` and `process.send()` used to operate
synchronously but became asynchronous in commit libuv/libuv@393c1c5
("unix: set non-block mode in uv_{pipe,tcp,udp}_open"), which landed
in io.js in commit 07bd05b ("deps: update libuv to 1.2.1").
