present: Move present_wnmd.c contents to hw/xwayland/xwayland-present.c
This will allow eliminating indirections and making the Xwayland Present code more efficient and easier to follow. While this technically changes the Xorg video driver ABI, I don't know of any drivers using the dropped present_wnmd_* symbols, and I doubt a Xorg driver could make use of them as is anyway. (As a bonus, Xorg no longer links any Xwayland specific Present code) v2: * Wrap DestroyWindow before initializing Present, so that present_destroy_window runs before xwl_present_cleanup. Avoids crash due to present_destroy_window calling xwl_present_* functions when xwl_present_window was already freed. (Olivier Fourdan) Acked-by: Olivier Fourdan <ofourdan@redhat.com>
