Fix egl_fb_read() to use the (destination) surface size instead of the
(source) framebuffer source for glReadPixels. Pass the DisplaySurface
instead of the pixeldata pointer to egl_fb_read() to make this possible.
With that in place framebuffer reads work fine even if the surface and
framebuffer sizes don't match, so we can remove the guest-triggerable
asserts in egl_scanout_flush().

This would help gtk-egl display showing scaled DMABuf cursor images when
gtk window was zoomed. A default scale of (1.0, 1.0) was presumed for
call sites where no scaling is needed.

We must set the correct context (via eglMakeCurrent) before
calling qemu_egl_create_context, so we need a thin wrapper and can't
hook qemu_egl_create_context directly as ->dpy_gl_ctx_create callback.

Add support for OpenGL ES to egl-helpers. Wire up the new option for
egl-headless and gtk UIs. egl-headless actually works fine. gtk hits a
not-yet implemented code path in libEGL when trying to use gles mode:
libEGL warning: FIXME: egl/x11 doesn't support front buffer rendering.
(This is mesa 17.2.3).

The cursor dmabuf can be NULL, in case no cursor defined by the guest.
Happens for example when linux guests show the framebuffer console.

Split the cursor callback into two, one for setting the dmabuf,
one for setting the position. Also add hotspot information.

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.

Add egl-headless user interface. It doesn't provide a real user
interface, it only provides opengl support using drm render nodes.
It will copy back the bits rendered by the guest using virgl back
to a DisplaySurface and kick the usual display update code paths,
so spice and vnc and screendump can pick it up.
Use it this way:
qemu -display egl-headless -vnc $display
qemu -display egl-headless -spice gl=off,$args
Note that you should prefer native spice opengl support (-spice
gl=on) if possible because that delivers better performance.
