wm4 923f353d2a win32: move global variables into a struct & some refactoring
This reflects the changes done to x11_common in mplayer2 some years
ago. It makes it possible to open multiple VOs at once.

The removed defines are probably for ancient versions of MinGW with
incomplete headers.

Remove some minor code duplication.
