revert e6188b2, use a loop instead the lock blocking wasn't consistent; fix issue where the FNE wouldn't check the heartbeat state of a peer that wasn't in a complete running state causing the peer to get into weird states; modify peer timeout handler, external peers (i.e. ISSI or upstream) and peer link peers get double the alotted maximum missed before being dropped;
