To avoid confusion and for accuracy going forward, we remove this method

establishment. If one wants to create a V1, funding outpoint-based
channel ID, then `ChannelId::v1_from_funding_outpoint` should be used
instead.

A large portion of the library has always made the assumption that having
the funding outpoint will always allow us to generate the channel ID.
This will not be the case anymore and we need to pass the channel ID along
where appropriate. All channels that could have been persisted up to this
point could only have used V1 establishment, so if some structures don't
store a channel ID for them they can safely fall back to the funding
outpoint-based version.

[bindings] No-export `RouteHopCandidate` lifetime'd fields

The bindings cannot express lifetimes, so exposing any field which
is a reference (and not `clone`-able, at least for garbage

Because log `Record`s are now being passed by ownership to `log`,
the bindings get quite annoyed that there's a lifetime hanging
around. We already don't use this lifetime in bindings (the
`FormatArgs` is converted to a string and stored on the heap), so
we can just drop the lifetime, even though it requires some
