A bunch of changes to get the server compiling on WIN32. mod_cgi, mod_include,

mod_isapi and mod_so don't work so I am not making them. Moved a lot of code out
of multithread.*  and into os.* (didn't want to add multithread to the new repository).
Much of this can be cleaned up when APR is stable.

And Dean's gonna but me for sure for the http_main hit. It's may be
possible to name a DLL entry point 'main()'. Just havent tried it yet.

Enjoy!
