Port to Windows. This is mostly glue layers for the poor POSIX support

on Windows. A few notes

 * Only sockets behave somewhat like file descriptors in UNIX.

 * There are no fixed paths. Closes thing is environment variables that point
   to system directories. We also figure out where the binary/dll is
   located and use that as configuration directory.
