Any extra draw call for the same blob resource representing guest scanout
before the previous drawing is not finished can break synchronous draw
sequence. To prevent this, drawing is now done only once for each draw
submission (when draw_submitted == true).

- removed mutex

This is a bugfix that stretches all the way back to January 2020,
where I initially introduced this problem and potential solutions.
A quick recap of the issue: QEMU did not sync up with the monitors
refresh rate causing the VM to render frames that were NOT displayed
to the user. That "fix" allowed QEMU to obtain the screen refreshrate
information from the system using GDK API's and was for GTK only.
Well, I'm back with the same issue again. But this time on Wayland.
And I did NOT realize there was YET another screen refresh rate
function, this time for Wayland specifically. Thankfully the fix was
simple and without much hassle.
Thanks,
Nikola
PS: It seems that my patch has gone missing from the mailing list,
hence I'm sending it again. Sorry for any inconveniences.

Create sync objects and fences only for dmabufs that are blobs. Once a
fence is created (after glFlush) and is signalled,
graphic_hw_gl_flushed() will be called and virtio-gpu cmd processing
will be resumed.

This has the following visible changes:
- GBM is required only for OpenGL dma-buf.
- X11 is explicitly required by gtk-egl.
- EGL is now mandatory for the OpenGL displays.
The last one needs some detailed description. Before this change,
EGL was tested only for OpenGL dma-buf with the check of
EGL_MESA_image_dma_buf_export. However, all of the OpenGL
displays depend on EGL and EGL_MESA_image_dma_buf_export is always
defined by epoxy's EGL interface.
Therefore, it makes more sense to always check the presence of EGL
and say the OpenGL displays are available along with OpenGL dma-buf
if it is present.

It is not used, and it is unlikely that a new use case will emerge
anytime soon because the scope of OpenGL contexts are limited due to
the nature of the frontend, VirGL, processing simple commands from the
guest.
Remove the function and ease implementing a new OpenGL backend a little.

Displaying rendered resources requires blocking qemu GPU to avoid extra
framebuffer copies. For an external display, via Spice currently, there
is a callback to block/unblock the rendering in the same thread.
But with the vhost-user-gpu backend, the qemu process doesn't handle
the rendering itself, and the blocking callback isn't effective.
Instead, the backend must be notified when the display code is done.
Fix this by adding a new GraphicHwOps callback to indicate the GL state
is flushed, and we are done manipulating the shared GL resources. Call
it from gtk and spice display.

With the upcoming dmabuf support in qemu there will be more users of the
shaders than just console-gl.c. So rename ConsoleGLState to
QemuGLShader, rename some functions too, move code from console-gl.c to
shaders.c.
No functional change.

The gd_gl_area_scanout_texture must destroy framebuffer if there is
no texture id instead of no framebuffer id.
The effect was a black screen with "-vga virtio -display gtk,gl=on"
options.

Rename the functions to to say "setup" instead of "create" because they
support being called multiple times on the same egl framebuffer.
Properly delete unused textures, update function interfaces to support
this.
