There is a lot of code in fwupd that just assigns a shared object type to a FuPlugin, and then for each device on that plugin assigns that same shared object to each FuDevice. Rather than proxy several kinds of information stores over two different levels of abstraction create a 'context' which contains the shared *system* state between the daemon, the plugins and the daemon. This will allow us to hold other per-machine state in the future, for instance the system battery level or AC state.
