WTF-PAD: Specify exit policy for machine conditions
From the TODO file:
- Specify exit policy for machine conditions?
- short_policy_t looks good, except for its flexible array member :/
- Can we make our own struct with a small, fixed number of policy
entries? Say 3-4? Or is that a bad idea to lose this flexibility?
- Check conditions based on attached streams on the circuit
- Accept should mean "only apply if matched"
- Reject should mean "don't apply if matched"
- If a policy is specified, Reject *:* is implicit default (so reject
policies need an Accept entry).
- With no policy, Accept *:* is implicit default.
