Is it ever necessary to override the total amount of video memory? I
think it would make most sense to add support for events and different
memory types to adapter_adjust_memory(), and then implement this
function on top of that one.

If we have wined3d_get_adapter_memory_info(), the memory information
in struct wined3d_adapter_identifier becomes redundant and could be
removed. I'd consider splitting this patch set in a slightly different
way, essentially introducing the wined3d functions in the same dxgi
patch that uses them. E.g., introducing
wined3d_get_adapter_memory_info() would be part of the patch that
modifies dxgi_adapter_QueryVideoMemoryInfo().

That looks like something that should use a free-list and
wined3d_array_reserve().
