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

Leftover from the early opengl days.
Unused now, so delete the dead code.

We'll add a variant which accepts dmabufs soon.  Change
the name so we can easily disturgish the two variants.

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}()
after dpy_gfx_replace_surface(con, NULL) was called in
virgl_cmd_set_scanout()

This allows virtio-gpu to render in 3d mode.
Uses egl, for gtk versions 3.14 and older.

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).
