Take 2: DDRAW: Fix reference counting

[Stefan Dösinger]

Hello,
This patch increases the reference count of a DirectDraw object when a Surface 
is created, like Windows does. It also adds a test which tests this 
functionality.

This time with the !FAILED() -> SUCCEEDED() suggestion from  
Robert Shearman. I kept adding a secound refcount in case of DDSCAPS_TEXTURE 
surfaces to achieve more compatiblity with Windows.
