Hello,
This is follow up to DRM native context v16 [1] and MAP_FIXED API v10 [2]
virtio-gpu patches that has been reviewed previously and were waiting for
a new release of libvirglrenderer 1.3.0.

Changelog:
v22:- Added r-b from Marc-André Lureau to ui/gdk patch.
- Corrected qemu_egl_create_context() to take explicit shared GL context
arg needed by gtk-egl display, as was suggested by Akihiko Odaki.
- Changed virtio-gpu BHs to use re-entrance guard as was suggested by
Akihiko Odaki.
Everything looks good to me. For the entire series:
Reviewed-by: Akihiko Odaki
v21:- Moved virtio-gpu to use iohandler_get_aio_context() as was
suggested by Akihiko Odaki.
- Updated EGL context-create helper and displays using it to make
helper take care of using appropriate parent GL context by itself,
without a need to switch GL context. Done it all in a single patch:
ui/egl: Don't change bound GL context when creating new context
- Cleaned up GDK context-restoring code as was suggested by Akihiko Odaki.
v20:- Adanbonded GL context unbinding approach as it created difficulties
with GTK assuming UI toolkit processed from a single thread. Omitted
all unbind-context patches and added new patch instead that makes
virtio-gpu to process cmds only from main-loop thread:
virtio-gpu: Bounce virtio_gpu_ctrl_bh() to main-loop thread
- Added r-b from Akihiko Odaki to reviewed v19 patches.
- Added patches restoring GL context when new ctx created for
dbus/spice/egl-headless displays.
v19:- Further improved improved naming of functions and terminology RE
GL context binding. Suggested by Akihiko Odaki.
- Added new patch "ui/gdk: Restore original context after new context
creation" in addition to improved "ui/sdl2: Restore original context"
that now getd actual bound GL context and restores to it instead
of restoring to the console's ctx, for consistency with the rest
of GL context management fixes that ensure context is bound only
when necessary.
- Improved virtio_gpu_virgl_update_render_state() with force_ctx_0()
and unbind_ctx() to make deferred GPU resetting maintain bound GL
context properly.
v18:- Changed dpy_gl_ctx_make_current() to use first scanout when unsetting
virgl's GL ctx0 and improved naming of cmd-processing function.
Suggested by Akihiko Odaki.
- Added "ui/gdk: Unset context after GL operations" patch after
realizing GDK/GL code needed more gdk_gl_context_clear_current().
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:
ui/sdl2: Unset context after GL operations
ui/gtk-egl: Unset context after GL operations
virtio-gpu: Unset context after GL operations
