Test program

The bug is still present for me with mesa 18.3.4-1
I wrote a little test program which compares an uploaded
3dtexture mipmap with the corresponding output of glGetTexImage.

It should output nothing, but on my desktop pc it outputs:

Error in level 2
Error in level 3
Error in level 4

Compile with "gcc test.c -o test -lglfw -lepoxy"
