onExit() is similar to the onLoad() callback. onExit() is called on each
module just before the process exits. This can be used to check state in
unit tests, but not to perform I/O. The process will forcibly exit as soon
as all of the onExit callbacks are made.
There is one major API change in the refactor: filename extensions are now
required when requiring or including modules.
Added extra test to test-module-loading.js.
If users do not send transfer-encoding or content-length headers, then I
will not add any additional. Content-Length: 0 is assumed if there aren't
other headers and chunked encoding is rare.
All the c++ code is now reduced to simple wrappers. The node.fs.File object
is defined entirely in javascript now. As is the actionQueue methods.
This makes the boundaries much cleaner. There is still some thought that
needs to go into how exactly the API should behave but this simplification
is a first step.
The error codes still remain for the two general file system operations:
rename and stat.
Additionally I've removed the actionQueue for file system operations. They
are sent directly into the thread pool.
Instead we're going to just get a single callback for the URI. This can be
parsed additionally in javascript using parseuri:

I haven't added that yet, but it will come soon.
Encoding UTF-16 (the native string representation) to UTF-8 is rather
expensive, however just chopping off the second bit to convert UTF-16 to
ASCII is rather fast. I've noticed major performance issues with
String::WriteUtf8 and thus I'm going to explicitly separate in the API.
Still need interfaces to this for the web server.
