[PATCH 1/4] ddraw: Keep an explicit reference to the wined3d device in surfaces.

[Henri Verbeet]

Version 1 and version 2 surfaces don't keep references to the ddraw interface
that created them, so such surfaces may get destroyed after the corresponding
ddraw object was destroyed. Wined3d requires that the device is destroyed
after all its resources are destroyed. In principle this issue always existed,
but it was probably made worse by changes in the texture cleanup code.
