[v9,0/5] support error handling mode

  This patchset introduce error handling mode concept, the supported modes 
are as follows:
1) PASSIVE: passive error handling, after the PMD detect that a reset 
is required, the PMD reports RTE_ETH_EVENT_INTR_RESET event, and
application invoke rte_eth_dev_reset to recover the port.

2) PROACTIVE: proactive error handling, after the PMD detect that a reset 
is required, the PMD reports RTE_ETH_EVENT_ERR_RECOVERING event, and do 
recovery internally, finally, reports the recovery result event.
