> Some customers want to know how much of the GPU time are their clients
> using in order to make dynamic load balancing decisions.
> 
> With the hooks already in place which track the overall engine busyness,
> we can extend that slightly to split that time between contexts.
> 
> v2: Fix accounting for tail updates.
> v3: Rebase.
> v4: Mark currently running contexts as active on stats enable.
> v5: Include some headers to fix the build.
