Was sending two packets instead of one for some short messages, and even 3,
for short chunked-encoded messages. Also use the more general Encode()
function for receiving HTTP bodies.

Gives ~6% improvement on "hello world" web server benchmarks.

Removes node.UTF8, node.RAW, node.ASCII enum versions of the encodings.
node.fs.read() now supports "raws" encoding.

Was causing send() to throw argument errors because arrays of ints would get
paired with the "raws" encoding. The bug was introduced in 8eb1294f.

In Snow Leopard "platform.machine()" returns "i386" while
"platform.architecture()" returns ('64bit',''). Using information from both
we can determine the proper architecture

This reverts commit ea29e137 re-enabling the
64bit build on Macintosh.

Instead of

  myemitter.emit("event", [arg1, arg2, arg3]);

the API is now

  myemitter.emit("event", arg1, arg2, arg3);

This change saves the creation of an extra array object for each event.
The implementation is also slightly more simple.

This reverts commit 412b4636.

Thanks to Felix Geisendörfer for the initial patch.

Problem appeared in dc39e820.

Appeared accidentally in 6dd850aa.

For faster "./node -v"

This allows you to have binary data imported into your application via
strings instead of arrays of numbers! This needs testing before release.

This does not (should not) change behavior.  Pulls those two functions
(encode/decode) out into node.cc.

This completes shebang support begun in
6acac912.

They were deprecated in 723c7d9f and
31265be4.

Still retaining error message.

I don't have access to this OS to fix the issue properly, so for the moment
I'm reverting back to 32bit build on Darwin. We changed to native 64bit in
8ddf9309.

Thanks to Johan Dahlberg and Tim Caswell for reporting and debugging this.
