[igt-dev] [RFC PATCH v10 4/6] lib: ioctl_wrappers: reach engines by index as well

[Chris Wilson]

> With the new engine query method engines are reachable through
> an index and context they are combined with.
> 
> The 'gem_has_ring()' becomes 'gem_context_has_engine()' that
> requires the index that the engine is mapped within the driver.
> 
> The previous 'gem_has_ring()' function becomes a wrapper to the new
> 'gem_context_has_engine()'.

gem_context_has_engine :=> ctx, engine

And reclaim from ioctl_wrappers.
