  CogVM source as per VMMaker.oscog-eem.2950

Fix huge horrible win32 Spur VM bug.  Plugins must export accessor depths (via
the EXPORT macro) otherwise the external primitive loading machinery will
silently compute their accessor depths as -1 (no accessor depth), and so no
primitives will be scanned for forwarders, and hence none will retry when given
forwarders, breaking the while Spur transparent forwarding mechanism for
primitives on win32.  The bug showed up with the new CameraPlugin
primSetCameraBuffers primitive which is given a newly becomed forwarder to a
pinned bitmap.  The primitive doesn't retry and hence always fails.
