Implement WGL extension to get fullscreen DC, use it in WineD3D

(In reply to comment #132)

I said (to Henri):

In looking at the code, I decided it makes more sense for the extension to
provide a full-screen DC which can then be used pretty much as normal.  The
attached patch adds a Wine WGL extension named WGL_WINE_fullscreen_dc.  It
provides two functions: wglCreateFullscreenDCWINE() and
wglDeleteFullscreenDCWINE().

The patch makes WineD3D aware of the extension and makes it use it instead of
GetDC()/wined3d_release_dc() if the swapchain is not windowed.

Then the extension is implemented in the Mac driver.

Taken together, this gets Worms Armageddon to show its rendering without the
use of any of its tweaks.  Since the extension hasn't been implemented for the
X11 driver it doesn't help there but, unlike my previous patch, it shouldn't
break X11 either.  It should work just like it has.  If the extension is
implemented for X11, then it should start working, too.
