[wined3d] seperate states part1

[Oliver Stieber]

Hi,
This patch is the first is a set of patches that separate the management of
DirectX states and openGL states.
Texture states are no longer set in IWineD3DDevice_SetTexture, they are now
set in drawPrimitiveUploadDirtyTextures, this has the advantage that states that change between
drawing calls are now reset and when a textures is set it doesn't have the current state applied,
just to be
changed reducing the number of state changed by up to 50%.

The patch introduces some regression with rendering to offscreen textures that
will be fixed as the state separation progresses.
