WineD3D state management

[H. Verbeet]

I had a very brief look at the code, pertially because a tarred up
directory isn't the most convenient way to spot what has changed and
what is still the same.

A few things I noticed:
  - markDirty() should probably either be a proper method of the
device, or have a prefix
  - "States" is a pretty generic name, probably want to prefix that as
well with something
  - Why are the state_* functions WINAPI?
  - "apply" is probably a better name than "func" in StateEntry wrt
making clear what it is supposed to do.

I'm still a bit uncertain about having all states together in a single array.
And I think a construction like:
DWORD stage = (state - STATE_TEXTURESTAGE(0, 0)) /
WINED3D_HIGHEST_TEXTURE_STATE;
in tex_colorop is quite ugly.
