Based-on: 20260214-region-v1-1-229f00ae1f38@rsg.ci.i.u-tokyo.ac.jp

Changelog:

v17:- Rebased patches on recent upstream, updated doc patches with new
      drm native contexts supported by libvirglrenderer.

    - Applied minor change that was requested from Akihiko Odaki
      by moving virtio_gpu_device_realize() for MAP_FIXED v10.

    - Added virtio_gpu_virgl_update_render_state() to virtio_gpu_fence_poll()
      that was missed in MAP_FIXED v10.

    - Added new patches fixing another GL context switching problem I ran
      into recently with virgl commands unexpectedly processed from CPU
      thread instead main-loop:
