Added prune protocol action + ProtocolAuthorization refactoring

[thehenrytsai]

1. Added support for prune protocol action.
2. Renamed "ancestor chain" to "record chain" because the chain often contains not just the ancestor records, but also record in concern which leads to confusion.
3. Simplified context and implementation of constructRecordChain()
4. Refactored authorizeAgainstAllowedActions() to make it more easily understood.

Got through most of it and it looks good!

Just a couple of NITS wrt naming/comments, but code logic looks solid.

Want to have another look at authorizeAgainstAllowedActions to make sure I understood it correctly and also review the tests before I stamp, but looks good so far!
