file locking for NT (an implementation)

[Jeff Kunce]

I've written a version of posixfile that implements
file locking for NT as well as UNIX. I realize that
the posixfile file locking API is deprecated, but it 
seemed the simplest route for a transparent cross-platform
solution.

I haven't done extensive tests on this - it's more a
proposal or example than a solution. Use at your own risk.
