Move userauth from thrmgr thread to conn handling threads, and do not enable r/w callbacks until userauth succeeds
...
Lock conn thread instead of thrmgr thread while adding conns (giant thrmgr lock versus conn thread level locks), so add conn thread mutex and remove thrmgr mutex
Offload thrmgr thread by moving many conn related setup to conn handling threads
Fix signal 6 crash caused by calling pxy_thrmgr_timer_cb() while failed conn is being freed, so use conn thread mutexes and defer adding conn to thr conn list until conn setup succeeds

...
Check retval of event_add() calls
Reduce frequency of userdb atime updates by not updating until idle time reaches more than half of user timeout value, otherwise privsep server can get very busy causing locked userdb
Do not care about multiple matches of IP addresses in arp cache on OpenBSD either
