Add an amount penalty to ProbabilisticScorer
The cost of large payments tends to be dominated by the channel fees. To
avoid this, add an amount penalty to ProbabilisticScorer with a user
configurable multiplier. The multiplier is applied for every 2^20th of
the amount weighted by the negative log10 of the channel's success
probability for the payment.

Avoid retrying over recently failed channels
In ProbabilisticScorer, the channel liquidity balance is reduced
whenever a payment fails at the corresponding channel. The payment may
still be retried through the channel, however, because the liquidity
penalty is capped. Use u64::max_value instead in this situation to avoid
retrying over the same path. This effectively makes u64::max_value the
penalty for amounts exceeding the upper bound, as well.
As an edge case, avoid using u64::max_value on attempts where the amount
is equal to the effective capacity, which may be the HTLC maximum when
the channel capacity is unknown.

Avoid needless MPP on multiple channels to the same first-hop
When we have many channels to the same first-hop, many of which do
not have sufficient balance to make the requested payment, but when
some do, instead of simply using the available channel balance we
may switch to MPP, potentially with many, many paths.
Instead, we should seek to use the smallest channel which can
easily handle the requested payment, which we do here by sorting
the first_hops in our router before beginning the graph search.
Note that the "real" fix for this should be to instead decide which
channel to use at HTLC-send time, as most other nodes do during
relay, but this provides a minimal fix without needing to do the
rather-large work of refactoring our HTLC send+relay pipelines.

Support receiving multiple funding_locked messages
As a part of adding SCID aliases to channels, we now have to accept
otherwise-redundant funding_locked messages which serve only to
update the SCID alias. Previously, we'd failt he channel as such
an update used to be bogus.

Provide our peers with SCID aliases and forward payments with them
This creates an SCID alias for all of our outbound channels, which
we send to our counterparties as a part of the `funding_locked`
message and then recognize in any HTLC forwarding instructions.
Note that we generate an SCID alias for all channels, including
already open ones, even though we currently have no way of
communicating to our peers the SCID alias for already-open
channels.

Handle `short_to_id` state updates on channel closure via macros
This avoids needing to update channel closure code in many places
as we add multiple SCIDs for each channel and have to track them.

Track SCID aliases from our counterparty and use them in invoices
New `funding_locked` messages can include SCID aliases which our
counterparty will recognize as "ours" for the purposes of relaying
transactions to us. This avoids telling the world about our
on-chain transactions every time we want to receive a payment, and
will allow for receiving payments before the funding transaction
appears on-chain.
Here we store the new SCID aliases and use them in invoices instead
of he "standard" SCIDs.

Clean up the `handle_monitor_err!()` macro argument forms somewhat
`handle_monitor_err!()` has a number of different forms depending
on which messages and actions were outstanding when the monitor
updating first failed. Instead of matching by argument count, its
much more readable to put an explicit string in the arguments to
make it easy to scan for the called form.

Make lightning-block-sync's init module slightly more generic
Users who want to use lightning-block-sync's init module would
be reasonable in wanting to use it in a multithreaded environment,
however because it takes a list of listeners as dyn chain::Listen
without any Send or Sync bound they fail in doing so.
Here we make the type bounds on `chain::Listen` generic across
`chain::Listen + ?Sized`, which the existing bound of `&dyn
chain::Listen` satisfies. Thus, this is strictly less restrictive
and allows for the use of `&dyn chain::Listen + Send + Sync`.
