Also fix two struct definitions

Ryan Houdek 5fdb66249b Linux: x86: Initial V3D and VC4 ioctl emulation 
Untested but with how the structs are laid out, it likely just works

Ryan Houdek 83b4188569 Microoptimization for the DRM ioctls 
For DRM applications have a three FD deep MRU cached for faster lookups of FD to DRM handlers.
In a completely DRM ioctl bound situation like es2gears or GL application without threaded context
Then this puts us /nearly/ at the performance of calling the ioctl32 handler directly.
Sadly there is overhead that can't be overcome so this is the best that can be done from userland

Ryan Houdek 9498a41f9b More ioctl32 emulation 
More DRM and i915 things, then wireless for some reason renderdoc relies on it
