This patch extends the currently proposed libeventdev API with support
for buffered enqueue operations.

This functionality can improve application performance when using event
devices that benefit from bulk enqueue operations, but due to its
architecture the application cannot easily combine its enqueue
operations.

For instance, consider a network application that dequeues a burst of
events and then processes them individually, where each event may be
processed and enqueued in a different codepath depending on its layer-3
or layer-4 protocol type. To take advantage of burst enqueues with the
current eventdev API, the application would have to be modified with an
ad-hoc buffering solution.

This functionality can be achieved fairly simply in the eventdev itself,
and in doing so reduces the amount of boilerplate code repeated among
applications of the sort described.

This patch applies on top of Jerin Jacob's eventdev API patchset[1].
