Following on from the refactoring of the rte_rings code done in the 17.05 release, it becomes relatively easy to create new ring implementations for data types other than "void *". The first candidate for this is the rte_event type, which being 16B in size, is small enough to be passed around directly rather than via pointer.
The SW eventdev implementation already defines an event ring implementation and this can be replaced by a more general implementation done in the eventdev library itself. However, feature parity between the SW eventdev implementation and a general rte_ring implementation is required, so support for rings of a defined size is added to the rte_ring library first.
