With rtnl socket we can track link status per port(except UDS port).
We can make sure we get the correct interface and latest status with function
port_link_status().
At the same time we need to set clock sde after link down. But we return
EV_FAULT_DETECTED in port_event(), which will not set clock sde. So we need
to set it in port_link_status().

This patch adds a new timer for use in 802.1AS-2011 applications. When
running as a slave in gPTP mode, the program must monitor both announce
and sync messages from the master. If either one goes missing, then we
trigger a BMC election. The sync timeout is actually reset by a valid
sync/follow up pair of messages.

This patch renames the per-port timer in order to make room in the
namespace for a timer that detects a sync message input timeout.

It was a cute idea to have the raw Ethernet layer use just one socket,
but it ended up not working on some specific PTP time stamping hardware.
