flow_control: implement pass / drop filtering policies
This change introduces a set of three modes for flow control
filters, one of which is default behavor and two extra modes
else described below:
- FILTER_POLICY_PASS_ALL
- FILTER_POLICY_DROP_ALL
Both modes are opposite, and make a filter either unconditionally
pass or drop all the data one gets to the input. They would be
usable for some external usage.
