  2. htlcswitch: add AddForward hodl breakpoint to switch 

    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.

  6. htlcswitch/mock: allow mockHopIterator to handle both normal and bl… 

    …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.
