Wow, thanks much for such a great write-up.  It will be very helpful
for me, although my goal is to get it work against all master
branches - AOSP, mesa3d, libdrm, drm_hwcomposer and gbm_gralloc.  Yes,
for gbm_gralloc, Rob has merged handle-rework-v2 into master.  And
kernel is 4.14.

I haven't got it all work, but the first thing I see different from
your side report is that, display is /dev/dri/card0 while gpu is
/dev/dri/card1.
