I had to pin the version of the LuaJIT library to a specific commit,
and have reworked the build scripts heavily to work with the XWin setup,
sacrificing the more flexible approach that existed before.
As such it is heavily customized to the specific usage here. There is no
reason to assume that it will be reconciled with the main project in the
future.
While this is an unstable dev release, its only significant change is
exactly the one I need: dropping `steam-vdf` and its out-of-date `nom`
dependency.
