For this particular exercise we can say that there are three loaders -
src/{gbm,glx,egl}, the interface is in include/ and everything else
can be considered* as dri module/drivers.

So here you want to split out the null checks into a separate patches,
which precede the functional (EGLimage) change. This way the former
can be applied (as they are bugfixes) for older versions of mesa.
