[DMSTYLE] Use Interlocked* functions in AddRef and Release

[Paul Vriens]

Hi,

Only d3d8 and d3d9 left! 4 other dll's contain TRACE's which I have to
look at.

Wherever possible, I changed the TRACE's not to contain This->*ref*
(without changing the text-part). No extra TRACE's added.

Not inlined because of size.

Changelog:
- use Interlocked* functions in AddRef and Release.
- store the result of the Interlocked functions and use only this.

Cheers,

Paul Vriens
