4112621420 egl-helpers: add alpha channel to texture format
Needed when rendering cursers which (unlike framebuffers)
actually are transparent.

0eb50c2737 egl-helpers: add egl_texture_blit and egl_texture_blend
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.

74083f9c01 egl: misc framebuffer helper improvements.
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.

e1913dbb58 egl-helpers: fix display init for x11
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

8bce03e393 ui/egl-helpers: fix egl 1.5 display init
Unfortunaly switching to getPlatformDisplayEXT isn't as easy as
implemented by 0ea1523fb6.  See the
longish comment for the complete story.

According to

if MESA_platform_gbm is supported display should be initialized
from a GBM handle using eglGetPlatformDisplayEXT.

14b6d44d47 Use scripts/clean-includes to drop redundant qemu/typedefs.h
Re-run scripts/clean-includes to apply the previous commit's
corrections and updates.  Besides redundant qemu/typedefs.h, this only
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.
