  This patch introduces a new version of the event timer adapter software
PMD [1]. In the original design, timer event producer lcores in the primary
and secondary processes enqueued event timers into a ring, and a service
core in the primary process dequeued them and processed them further.  To
improve performance, this version does away with the ring and lets lcores in
both primary and secondary processes insert timers directly into timer
skiplist data structures; the service core directly accesses the lists as
well, when looking for timers that have expired. (This behavior requires
the patch to the timer library that is referenced below.)
