[PATCH] wmvcore/tests: Access IWMDRMReader(|2|3) interfaces on Windows.

[Jefferson Carpenter]

That code would almost certainly crash if run against Wine's wmvcore.dll.
It is just to have a piece of physical evidence that there IS a way to
access the DRM interfaces.  It would of course be removed, once the
mechanism by which DRM interfaces are exposed is understood, and Wine
implements the corresponding functionality.

Applications normally access this by being linked with a lib called
wmdrmstub.lib access to which is restricted by Microsoft, instead of with
the wmvcore.lib that anybody can get.  I do not know what the differences
are between those libs, e.g. how WMCreateReader comes to produce a reader
that exposes a IWMDRMReader interface when you link with one but not the
other.
