Merge remote-tracking branch 'joyent/v0.12' into v1.x

I was originally going to do this after the v0.11.15 release, but as
that release is three weeks overdue now, I decided not to wait any
longer; we don't want the delta to get too big.

Conflicts:
	lib/net.js
	test/simple/simple.status

+### `Intl` (ECMA-402) support:
 
-*Note:* more docs, including how to reduce disk footprint, are on
+[Intl](https://github.com/joyent/node/wiki/Intl) support is not
+enabled by default.
+
+#### "small" (English only) support
+
+This option will build with "small" (English only) support, but
+the full `Intl` (ECMA-402) APIs.  With `--download=all` it will
+download the ICU library as needed.
+
+Unix/Macintosh:
+
+```sh
+./configure --with-intl=small-icu --download=all
+```
+
+Windows:
+
+```sh
+vcbuild small-icu download-all
+```
+
+The `small-icu` mode builds
+with English-only data. You can add full data at runtime.
+
+*Note:* more docs are on
 [the wiki](https://github.com/joyent/node/wiki/Intl).
 
-#### Use existing installed ICU (Unix/Macintosh only):
+#### Build with full ICU support (all locales supported by ICU):
+
+With the `--download=all`, this may download ICU if you don't
+have an ICU in `deps/icu`.
+
+Unix/Macintosh:
 
 ```sh
-pkg-config --modversion icu-i18n && ./configure --with-intl=system-icu
+./configure --with-intl=full-icu --download=all
 ```
 
-#### Build ICU from source:
+Windows:
 
-First: Unpack latest ICU
-  [icu4c-**##.#**-src.tgz](http://icu-project.org/download) (or `.zip`)
-  as `deps/icu` (You'll have: `deps/icu/source/...`)
+```sh
+vcbuild full-icu download-all
+```
+
+#### Build with no Intl support `:-(`
+
+The `Intl` object will not be available.
+This is the default at present, so this option is not normally needed.
 
 Unix/Macintosh:
 
 ```sh
-./configure --with-intl=full-icu
+./configure --with-intl=none
 ```
 
 Windows:
 
+```sh
+vcbuild intl-none
+```
+
+#### Use existing installed ICU (Unix/Macintosh only):
+
+```sh
+pkg-config --modversion icu-i18n && ./configure --with-intl=system-icu
+```
+
+#### Build with a specific ICU:
+
+You can find other ICU releases at
+[the ICU homepage](http://icu-project.org/download).
+Download the file named something like `icu4c-**##.#**-src.tgz` (or
+`.zip`).
+
+Unix/Macintosh: from an already-unpacked ICU
+
+```sh
+./configure --with-intl=[small-icu,full-icu] --with-icu-source=/path/to/icu

+
