[0/3] d3dx9: stubs for D3DXGetImageInfo

[Tony Wasserka]

This patch series adds the files surface.c and util.c.
General notes:
- surface.c will contain the function definitions for D3DXGetImageInfo
and D3DXLoadSurface.
- D3DXGetImageInfo can't be forwarded to the D3DX8 version, as the
D3DXIMAGE_INFO structure changed (as did the range of supported formats,
too)
- The LoadFileIntoMemory and LoadResourceIntoMemory functions will be
used for many other function groups, e.g. D3DXLoadSurface,
D3DXCreateTexture, D3DXLoadMesh, etc...
