This new hodl flag will prevent the switch from opening circuits for ADDs it's attempting to forward. This simulates arbitrary delays in the switch during forwarding and can be leveraged to test the switch going down while trying to forward a batch of HTLCs.
…dpkg We expand our tests to verify that a forwarding node which receives a blinded HTLC (bob) is able to restore the blinding point from disk. NOTE: He's only able to do so if he's revoked his local commitment.

…ind hops We expand the capability of the mockHopIterator such that it is able to handle both normal and blind hops. The destinction is made via a check for sentinel value which delineates the byte boundary between serialized hops. The implemenation is functional yet somewhat propietary in the sense that it is specific to handling blind hops and not as general as it could be. This lack of generality leaves the door open to eventual inclusion of the full blown TLV serialization scheme into the mock iterator. Without this or something like TLV we do not have a way to know whether we should or even how to deserialize a variable length field like the route blinding payload. htlcswitch/mock: use TLV for route blinding payload Allow the mock hop iterator to use TLV for the route blinding deserialization. We assume the route blinding payload is already serialized via TLV and add a length prefix before so it can be properly parsed from the onion packet.

Change Description
Here's a not quick and very dirty set of commits which try to determine whether or not we need to worry about recovering blinding point from forwarding packages now that we persist HTLC extra data to disk as part of channldb.HTLC.
If you try adding and removing the last commit, you'll notice that the payment fails.
-vwhich kind of show what's going on.NOTE: This is NOT intended for inclusion or merging alongside the rest of the route blinding code! Rather, it is meant to aid discussion on the relevance of restoring blinding points from forwarding packages!
