First draft only contained the Vulkan rendering part. This revision
adds the remaining bits: importing the memory to GL, creating a texture
for it and sampling it.
While there is now a fair bit of infrastructure that can be re-used, I
feel that a lot more work remains.
This is a pretty great start.
Along the way I needed GL support and drafted some initial support for
Intel Mesa driver:

Jason: I was wondering how GL drivers are meant to deduce the tiling.
I suppose this is meant to happen outside the GL-api but I
couldn't think of anything else than trying to read that from
the buffer object (see the Intel driver hook).
I can't speak for igt, but on the radeonsi side these are passed as
metadata associated with the kernel bo.

Can someone suggest a better location to place this file. Would
tests/util work?
Interacting with vulkan would be useful even outside the
ext_memory_object case.
