The old error handling code checked if the return value of Socket::Send() != 0,
which is wrong because Socket::Send() can write less bytes than requested or
return -1 on error.

It is not needed for v8 3.10, and actually breaks the build.
This reverts commit bd33fea7.

The v8 team apparently decided that all build products should go
into ./build/«type», and updated their common.gypi file to do so.
Unfortunately v8's common.gypi is only used for some targets. All
the other targets would still look in the old place to find their
their dependencies, which effectively broke the build.

In the long run it would be good for node to send all build
output to ./build too, on all platforms.

Callbacks that were passed to the binding layer ran in the context of the
(internal) binding object. Make sure they run in the global context.

Before:

  fs.symlink('a', 'b', function() {
    console.log(this); // prints "{ oncomplete: [Function] }"
  });

After:

  fs.symlink('a', 'b', function() {
    console.log(this); // prints "{ <global object> }"
  });

Fix a bug where fs.symlink('foo', 'bar') executed symlink(2) synchronously.

This prevents node-gyp from attempting to download dev header files from
nodejs.org. Instead, the files in this repo will be used to build the module.

Create slab allocator when binding is initialized.

Add an AtExit handler to destroy the slab before the VM shuts down, it can't be
disposed when V8 is dead and Valgrind will complain about memory leaks.

Don't try to dispose the persistent handles if the VM is already dead, it
triggers an assertion inside V8.

Closes #3366

The current WiX project files do some manual processing and generation
which WiX supports doing out of the box. This patch will use the
HeatDirectory task to generate the npm.wxs file and use the auto GUID
generation. I also changed the msi filename generation to include the
version number to match the currently used name for released msi files.
