Expose `onion_message` items directly rather than via re-exports

When we originally added the `onion_message` module, there weren't
a lot of public items in it, and it didn't make a lot of sense to
export the whole sub-module structure publicly. So, instead, we
exported the public items via re-exports directly in the
`onion_message` top-level module. However, as time went on, more
and more things entered the module, which left the top-level module
rather cluttered.

Worse, in 0.0.119, we exposed
`onion_message::messenger::SendSuccess` via the return type of
`send_message`, but forgot to re-export the enum itself, making
it impossible to actually use from external code.

Here we address both issues and simply replace the re-export with
the underlying sub-module structure.

requires having a concrete `PeerManager` type which does *not* use
`UtxoLookup` in the `RoutingMessageHandler` type, this broke users
who were directly using `P2PGossipSync`.

We could split `UtxoLookup` into two, with different bounds, for
the two use-cases, but instead here we simply switch to storing a
reference to the `PeerManager` via a `dyn Fn` which allows us to

Stop including dust values in feerate affordability checks

When we or our counterparty are updating the fees on the channel,
we currently check that the resulting balance is sufficient not
only to meet the reserve threshold, but also not push it below
dust. This isn't required in the BOLTs and may lead to spurious
force-closures (which would be a bit safer, but reserve should
always exceed the dust threshold).

Worse, the current logic is broken - it compares the output value
in *billionths of satoshis* to the dust limit in satoshis. Thus,
the code is borderline dead anyway, but can overflow for channels
with several million Bitcoin, causing the fuzzer to get mad (and
lead to spurious force-closures for few-billion-dollar channels).
