net: Make server.connections un-enumerable

The property server.connections should no longer be enumerable because
it has been deprecated. This will prevent deprecation warnings when
server objects are accessed by functions such as JSON.stringify.

doc: fix brackets for optional parameters

Documentation incorrectly used bracket notation for optional parameters.
This caused inconsistencies in usage because of examples like the
following:

    fs.write(fd, data[, position[, encoding]], callback)

This simply fixes all uses of bracket notation in documentation.

timer_wrap: remove HandleScopes, check return size

Calls from JS to C++ have an implicit HandleScope. So there is no need
to instantiate a new HandleScope in these basic cases.

Check if the returned int64_t is an SMI and cast the return value to
uint32_t instead of a double. Prevents needing to box the return value,
and saves a small amount of execution time.

buffer: fix and cleanup fill()

Running fill() with an empty string would cause Node to hang
indefinitely. Now it will return without having operated on the buffer.

User facing function has been pulled into JS to perform all initial
value checks and coercions. The C++ method has been placed on the
"internal" object.

Coerced non-string values to numbers to match v0.10 support.

Simplified logic and changed a couple variable names.

Added tests for fill() and moved them all to the beginning of
buffer-test.js since many other tests depend on fill() working properly.

build, i18n: improve Intl build, add "--with-intl"

The two main goals of this change are:
 - To make it easier to build the Intl option using ICU (particularly,
   using a newer ICU than v8/Chromium's version)
 - To enable a much smaller ICU build with only English support The goal
   here is to get node.js binaries built this way by default so that the
   Intl API can be used. Additional data can be added at execution time
   (see Readme and wiki)

More details are at https://github.com/joyent/node/pull/7719

In particular, this change adds the "--with-intl=" configure option to
provide more ways of building "Intl":
 - "full-icu" picks up an ICU from deps/icu
 - "small-icu" is similar, but builds only English
 - "system-icu" uses pkg-config to find an installed ICU
 - "none" does nothing (no Intl)

For Windows builds, the "full-icu" or "small-icu" options are added to
vcbuild.bat.

Note that the existing "--with-icu-path" option is not removed from
configure, but may not be used alongside the new option.

Wiki changes have already been made on
 https://github.com/joyent/node/wiki/Installation
and a new page created at
 https://github.com/joyent/node/wiki/Intl
(marked as provisional until this change lands.)

Summary of changes:

* README.md : doc updates

* .gitignore : added "deps/icu" as this is the location where ICU is
  unpacked to.

* Makefile : added the tools/icu/* files to cpplint, but excluded a
  problematic file.

* configure : added the "--with-intl" option mentioned above.
  Calculate at config time the list of ICU source files to use and data
  packaging options.

* node.gyp : add the new files src/node_i18n.cc/.h as well as ICU
  linkage.

* src/node.cc : add call into
  node::i18n::InitializeICUDirectory(icu_data_dir) as well as new
  --icu-data-dir option and NODE_ICU_DATA env variable to configure ICU
  data loading. This loading is only relevant in the "small"
  configuration.

* src/node_i18n.cc : new source file for the above Initialize..
  function, to setup ICU as needed.

* tools/icu : new directory with some tools needed for this build.

* tools/icu/icu-generic.gyp : new .gyp file that builds ICU in some new
  ways, both on unix/mac and windows.

* tools/icu/icu-system.gyp : new .gyp file to build node against a
  pkg-config detected ICU.

* tools/icu/icu_small.json : new config file for the "English-only" small
  build.

* tools/icu/icutrim.py : new tool for trimming down ICU data. Reads the
  above .json file.

* tools/icu/iculslocs.cc : new tool for repairing ICU data manifests
  after trim operation.

* tools/icu/no-op.cc : dummy file to force .gyp into using a C++ linker.

* vcbuild.bat : added small-icu and full-icu options, to call into
  configure.

* Fixed toolset dependencies, see
  https://github.com/joyent/node/pull/7719#issuecomment-54641687

Note that because of a bug in gyp {CC,CXX}_host must also be set.
Otherwise gcc/g++ will be used by default for part of the build.

node: avoid automatic microtask runs

Since we are taking control of the microtask queue it makes sense to
disable autorun and only run microtasks when necessary. Just setting
isolate->SetAutorunMicrotasks(false) would cause _tickCallback() not to
be called.

Automatically running the microtask queue will cause it to run:

* After callback invocation
* Inside _tickCallback()
* After _tickCallback() invocation

The third one is unnecessary as the microtask queue is guaranteed to be
empty at this point. The first only needs to be run manually when
_tickCallback() isn't going to be called by MakeCallback().
