[PATCH v2 0/46] MR1010: Draft: opengl32: Path towards wow64 support.

[Rémi Bernon]

I was watching some random YouTube stream and then heard a voice telling me to do this.

This can run wglgears on wow, though there's plenty of missing pieces which I don't have any idea how to fix (like buffer mapping, etc.). Opening it as a draft for now to show the whole thing, if it seems alright I'll send it in batches.

Rebased and updated with some implementation of WOW64 thunks, and Map/Unmap copies. It needs the WINEWOW change from jacek branch, and some hacks in wined3d to ignore (harmless?) D3DKMT failures and disable persistent buffer mapping.
