multi: do not use tlv.Record outside wire format handling
This commit prepares for more manipulation of custom records. A list of
tlv.Record types is more difficult to use than the more basic
map[uint64][]byte.

Furthermore fields and variables are renamed to make them more
consistent.

routing/route/route: add optional MPP field to Hop
This commit also modifies the Router serialization to persist the MPP
struct when present, and properly restore it when loading from disk.

routing/route/route: prevent modification of hop.TLVRecords
Currently the underlying array backing the hop's TLVRecords is modified
when combining custom records with the primitive forwarding info. This
commit uses a fresh slice to prevent modifications from mutating the
hop itself.

routing/route+tlv: add new TLV-EOB awareness to Hop+Route
In this commit, we extend the Hop struct to carry an arbitrary set of
TLV values, and add a new field that allows us to distinguish between
the modern and legacy TLV payload.

We add a new `PackPayload` method that will be used to encode the
combined required routing TLV fields along any set of TLV fields that
were specified as part of path finding.

Finally, the `ToSphinxPath` has been extended to be able to recognize if
a hop needs the modern, or legacy payload.

route: return 0 fee from TotalFees for empty route.
Otherwise we would crash calling the method on empty routes.

router: convert Route.ToHopPayloads() to Route.ToSphinxPath()
In this commit, we update the process that we use to generate a sphinx
packet to send our onion routed HTLC. Due to recent changes in the
`sphinx` package we use, we now need to use a new PaymentPath struct. As
a result, it no longer makes sense to split up the nodes in a route and
their per hop paylods as they're now in the same struct. All tests have
been updated accordingly.
