[Mesa-dev] [PATCH 5/5] egl/dri2: add image extension such it's usable by swrast driver

[Gurchetan Singh]

Otherwise, this extension is not visible to the EGL users who
use the swrast driver.

This will allow the swrast driver to use eglCreateImageKHR,
provided the target is EGL_GL_TEXTURE_2D_KHR or
EGL_GL_RENDERBUFFER_KHR.  Note we still have to implement the
create from render buffer path.

v2: add it to optional_core_extensions instead of swrast_core_extensions,
    so it's not a requirement (Emil)
v3: Merge egl/dri2 changes together, also add support for
    platform_wayland (Emil)
