v2:
* Addressed both comments from Yi He
* Fixed a clang compilation issue
Optimized scheduler priority queue and packet IO poll queue implementation
with a ring based data structure. Scheduler performance is improved tens of
percents in a typical test case. Also there's no more dependency to pools,
buffer and queue APIs.
