Right now the ActiveRender code in D3D8 requests a GLX_DEPTH_SIZE of
32 in case the direct3d color format also has a depth of 32. As
verified on various linux drivers (Ati fglrx, Ati (dri) and Nvidia)
the color depth needs to be 24. This patch sets the depth to 24 and it
fixes bugs in 3dmark2001 and other programs.

ReadDirectoryChangesW remembers whether it's recording changes or not.
Don't initialize overlapped->InternalHigh.
The hEvent is cleared when ReadDirectoryChanges is called.

The current method of handling typelib-marshaled interfaces that derive
from IDispatch is to query for an IDispatch pointer from the proxy, but
this causes a circular reference count.
Fix the reference counting by loading using the IRpcProxyBuffer of
IDispatch without an outer unknown, so that the lifetime is controlled
by the typelib-marshaled interface's proxy. The IDispatch proxy now
shares the same channel as the typelib-marshaled interface, so fix up
the stub side to handle this.

Make the VT_DISPATCH and VT_UNKNOWN cases of serialize_param match the
TKIND_INTERFACE case below by releasing their respective interfaces as
necessary.

StdProxy_Construct as it will just crash anyway.
