build: i18n: add icu config options

Make "--with-intl=none" the default and add "intl-none" option to
vcbuild.bat.

If icu data is missing print a warning unless either --download=all or
--download=icu is set. If set then automatically download, verify (MD5)
and unpack the ICU data if not already available.

There's a "list" of URLs being used, but right now only the first is
picked up. The logic works something like this:

* If there is no directory deps/icu,
  * If no zip file (currently icu4c-54_1-src.zip),
    * Download zip file (icu-project.org -> sf.net)
  * Verify the MD5 sum of the zipfile
    * If bad, print error and exit
  * Unpack the zipfile into deps/icu
* If deps/icu now exists, use it, else fail with help text

Add the configuration option "--with-icu-source=..."

Usage:
  * --with-icu-source=/path/to/my/other/icu
  * --with-icu-source=/path/to/icu54.zip
  * --with-icu-source=/path/to/icu54.tgz
  * --with-icu-source=http://example.com/icu54.tar.bz2

Add the configuration option "--with-icu-locals=...".  Allows choosing
which locales are used in the "small-icu" case.

Example:
    configure --with-intl=small-icu --with-icu-locales=tlh,grc,nl

(Also note that as of this writing, neither Klingon nor Ancient Greek
are in upstream CLDR data. Serving suggestion only.)

Don't use hard coded ../../out paths on windows. This was suggested by
@misterdjules as it causes test failures.  With this fix, "out" is no
longer created on windows and the following can run properly:

    python tools/test.py simple

Reduce space by about 1MB with ICU 54 (over without this patch). Also
trims a few other source files, but only conditional on the exact ICU
version used. This is to future-proof - a file that is unneeded now may
be needed in future ICUs.

Also:
  * Update distclean to remove icu related files
  * Refactor some code into tools/configure.d/nodedownload.py
  * Update docs
  * Add test

stream: switch _writableState.buffer to queue

In cases where many small writes are made to a stream
lacking _writev, the array data structure backing the
WriteReq buffer would greatly increase GC pressure.

Specifically, in the fs.WriteStream case, the
clearBuffer routine would only clear a single WriteReq
from the buffer before exiting, but would cause the
entire backing array to be GC'd. Switching to [].shift
lessened pressure, but still the bulk of the time was
spent in memcpy.

This replaces that structure with a linked list-backed
queue so that adding and removing from the queue is O(1).
In the _writev case, collecting the buffer requires an
O(N) loop over the buffer, but that was already being
performed to collect callbacks, so slowdown should be
neglible.

async-wrap: add event hooks

Call a user-defined callback at specific points in the lifetime of an
asynchronous event. Which are on instantiation, just before/after the
callback has been run.

**If any of these callbacks throws an exception, there is no forgiveness
or recovery. A message will be displayed and a core file dumped.**

Currently these only tie into AsyncWrap, meaning no call to a hook
callback will be made for timers or process.nextTick() events. Though
those will be added in a future commit.

Here are a few notes on how to make the hooks work:

- The "this" of all event hook callbacks is the request object.

- The zero field (kCallInitHook) of the flags object passed to
  setupHooks() must be set != 0 before the init callback will be called.

- kCallInitHook only affects the calling of the init callback. If the
  request object has been run through the create callback it will always
  run the before/after callbacks. Regardless of kCallInitHook.

- In the init callback the property "_asyncQueue" must be attached to
  the request object. e.g.

  function initHook() {
    this._asyncQueue = {};
  }

- DO NOT inspect the properties of the object in the init callback.
  Since the object is in the middle of being instantiated there are some
  cases when a getter is not complete, and doing so will cause Node to
  crash.

async-wrap: explicitly pass parent

When instantiating a new AsyncWrap allow the parent AsyncWrap to be
passed. This is useful for cases like TCP incoming connections, so the
connection can be tied to the server receiving the connection.

Because the current architecture instantiates the *Wrap inside a
v8::FunctionCallback, the parent pointer is currently wrapped inside a
new v8::External every time and passed as an argument. This adds ~80ns
to instantiation time.

A future optimization would be to add the v8::External as the data field
when creating the v8::FunctionTemplate, change the pointer just before
making the call then NULL'ing it out afterwards. This adds enough code
complexity that it will not be attempted until the current approach
demonstrates it is a bottle neck.

build: i18n: fix icu toolset dependencies

So what I did here is to make the icutools library actually contain the
entire ICU dependencies needed for host-side tools. Sadly, this will
build ICU twice, but avoids conflicts between host and target side.
This all seems like a gyp bug of some sort, but without docs for
toolsets, who’s to say?

I removed the icuio library as a separate target, because it was only
used by the host-side tools.

build: fix build for SmartOS

This change in V8: https://code.google.com/p/v8/source/detail?r=22210
has introduced a method named OS::GetCurrentThreadId which fails to
compile on OSes where a "gettid" syscall does not exist.

This build issue has been fixed upstream by several changes:
- https://code.google.com/p/v8/source/detail?r=23459.
- https://codereview.chromium.org/649553002
- https://codereview.chromium.org/642223003

Another minor fix to the upstream changes was also necessary.
See https://code.google.com/p/v8/issues/detail?id=3620 for
more information.

The other build issue was due to the fact that alloca.h is not included
by other system includes on SmartOS, which is assumed by V8.

Built and tested on Linux, MacOS X, Windows and SmartOS.

* After _tickCallback() invocation

The third one is unnecessary as the microtask queue is guaranteed to be
