 Summary: Ensure default TCP flags are applied to rules like 'pass stateful all'
 The documented default "flags S/SAFR" for stateful rules that affect
 TCP packets but don't specify any flags, doesn't actually get applied
 to a rule like "pass stateful out all". The big problem with this is
 that when you then do a "block return-rst" for an incoming packet, the
 generated RST packet will create state for the connection attempt it's
 blocking, so that a second attempt from the same source will pass.
 This change makes the default flags actually apply to such simple
 rules.  It also fixes a related bug in the code generation for the
 flag matching, where part of the action could erroneously be omitted.
