docs are too terse and did not have the list of valid timeout states.
While at it, adjust default stream timeout of udp to 120, this is the
current kernel default.

+tcp connection state names that can have a specific timeout value are:
+
+'close', 'close_wait', 'established', 'fin_wait', 'last_ack', 'retrans', 'syn_recv', 'syn_sent', 'time_wait' and 'unack'.
+
+You can use 'sysctl -a |grep net.netfilter.nf_conntrack_tcp_timeout_' to view and change the system-wide defaults.
+'ct timeout' allows for flow-specific settings, without changing the global timeouts.
+
+For example, tcp port 53 could have much lower settings than other traffic.
+
+udp state names that can have a specific timeout value are 'replied' and 'unreplied'.
