Recover the complicated situation after my bad merge
I made a mistake merge.  Reverting it in c778945806 undid the state
on master, but now I realize it crippled the git merge mechanism.
As the merge contained a mix of commits from `master..staging-next`
and other commits from `staging-next..staging`, it got the
`staging-next` branch into a state that was difficult to recover.

I reconstructed the "desired" state of staging-next tree by:
 - checking out the last commit of the problematic range: 4effe769e2
 - `git rebase -i --preserve-merges a8a018ddc0` - dropping the mistaken
   merge commit and its revert from that range (while keeping
   reapplication from 4effe769e2)
 - merging the last unaffected staging-next commit (803ca85c20)
 - fortunately no other commits have been pushed to staging-next yet
 - applying a diff on staging-next to get it into that state

/** Packaging design:
- The basic mesa ($out) contains headers and libraries (GLU is in libGLU now).
This or the mesa attribute (which also contains GLU) are small (~ 2 MB, mostly headers)
and are designed to be the buildInput of other packages.
- DRI drivers are compiled into $drivers output, which is much bigger and
depends on LLVM. These should be searched at runtime in
"/run/opengl-driver{,-32}/lib/*" and so are kind-of impure (given by NixOS).
(I suppose on non-NixOS one would create the appropriate symlinks from there.)
- libOSMesa is in $osmesa (~4 MB)

The Mesa project began as an open-source implementation of the OpenGL
specification - a system for rendering interactive 3D graphics. Over the
years the project has grown to implement more graphics APIs, including
OpenGL ES (versions 1, 2, 3), OpenCL, OpenMAX, VDPAU, VA API, XvMC, and
Vulkan. A variety of device drivers allows the Mesa libraries to be used
in many different environments ranging from software emulation to
complete hardware acceleration for modern GPUs.
