Fwd: Add d3d11_CreateDeviceAndSwapChain

[Martell Malone]

This is the explanation for the d3d11 patch I submitted to wine-patches.
Stefan said Henri might have an interest so I should post the explanation
here

Comments are welcome :)

Whoops that sent without my comments

In the d3d code we use use 8 byte extran indentation for continued lines:

I have sent an updated patch to reflect this.

I'm curious, does this improve the behavior of some application? E.g. game
> X now falls back to d3d9 without crashing due to the stub?

My main focus for writing this was for the mingw-w64 project that imports
the headers and libs from wine.
We were just casually missing 1 of the 3 most important functions so I sent
in this patch :)

There are 2 ways to create a device and swapchain however. You can do them
seperatly or this function does them both at once.
I assume that this returns the correct error like CreateDevice so that if
the application has a fallback it can use it.
So thats highly possible.

Kind Regards
Martell
