In egl mode the scale_x and scale_y variables are not set, so the
scaling logic in the mouse motion event handler does not work.

Fix that.  Also scale the cursor position in gd_egl_cursor_position().

GTK2 was deprecated in the 2.12.0 release with:

  commit b7715af2
  Author: Daniel P. Berrange <berrange@redhat.com>
  Date:   Tue Dec 12 11:34:40 2017 +0000

    ui: deprecate use of GTK 2.x in favour of 3.x series

    The GTK 3.0 release was made in Feb, 2011:

      https://blog.gtk.org/2011/02/10/gtk-3-0-released/

    That will soon be 7 years ago, which is enough time to consider
    the 3.x series widely supported.

    Thus we deprecate the GTK 2.x support, which will allow us to
    delete it in the last release of 2018. By this time, GTK 3.x
    will be almost 8 years old.

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).

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.

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.

When running on gtk we need X11 platform not mesa platform.
Create separate functions for mesa and x11 so we can keep
the egl #ifdef mess local to egl-helpers.c

Spice client needs the whole GL texture dimension to be able to show a
scanout with a monitor offset (different than +0+0).

Furthermore, this fixes a crash when calling surface_{width,height}()

This adds opengl rendering support to the gtk ui, using egl.
It's off by default for now, use 'qemu -display gtk,gl=on'
to play with this.

Note that gtk got native opengl support with release 3.16.
There most likely will be a separate implementation for 3.16+,
using the native gtk opengl support.  This patch covers older
versions (and for the time being 3.16 too, hopefully without
rendering quirks).
