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

[Andi Shyti]

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()'.
