Windows GL drivers are notoriously not very good. Otoh, ANGLE provides
rock solid GLES implementation on top of direct3d. We should recommend
it and default to ES when using EGL (users can easily override this if
necessary)

Future patches will introduce EGL support on win32 (too late for 8.0
though). Having a common place for EGL initialization and error handling
will make it simpler.

eb_fb_blit should be able to blit partial image of guest display (blob res)
in case multiple displays are configured for the guest and they are set as extended-
desktop mode.
v2: egl_fb includes dmabuf info then make egl_fb_blit position and size
parameters programmed in dmabuf structure (previously position/size
parameters were given to egl_fb_blit separately)

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.

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.

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).

egl_texture_blit() blits a texture, simliar to egl_fb_blit() but by
rendering the texture to the screen instead of using a framebuffer blit.
egl_texture_blend() renders a texture with alpha blending, will be used
to render the cursor to the screen.

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.

Re-run scripts/clean-includes to apply the previous commit's

finds a redundant config-host.h include in ui/egl-helpers.c. No idea
how that escaped the previous runs.
Some manual whitespace trimming around dropped includes squashed in.
