 Modified Files:
        src/usr.sbin/ypbind: ypbind.c
 
 Log Message:
 Instead of using magic numbers in what looks like a boolean
 (dom_alive), create a state enumeration (domainstates) and use it
 instead.
 
 Instead of three states (new, alive, and, effectively, 'troubled') go
 to five: new, alive, pinging, lost, and dead.
 
 Domains start in the NEW state. When we get a reply from a server, the
 state goes to ALIVE. The state is set to PINGING when we ping the
 server (once a minute normally) and if the ping times out, it goes to
 LOST. If we stay lost for a minute, go to DEAD, and in DEAD, do
 exponential backoff of nag_servers calls.
 
 Getting rid of the broken logic attached to the 'troubled' state fixes
 PR 15355 (ypbind defeats disk idle spindown) -- it will now only
 rewrite the binding file when the binding changes.
 
 Also, fix the HEURISTIC code so it doesn't trigger except in ALIVE
 state. I think this was the source of a lot of the spamming behavior
 seen in PR 32519, which is now fixed.
 
 Might also fix PR 23135 (broadcast ypbind sometimes fails to find
 servers).
