As part of the ongoing async signer work, our holder signatures must
also be capable of being obtained asynchronously. We expose a new
`ChannelMonitor::signer_unblocked` method to retry pending onchain
claims by re-signing and rebroadcasting transactions. Unfortunately, we
cannot retry said claims without them being registered first, so if
we're not able to obtain the signature synchronously, we must return the
transaction as unsigned and ensure it is not broadcast.
This method is meant to be used as a last resort when a user is forced
to broadcast the current state, even if it is stale, in an attempt to
claim their funds in the channel. Previously, we'd return the commitment
and HTLC transactions such that they broadcast them themselves. Doing so
required a different code path, one which was not tested, to obtain
these transactions than our usual path when force closing. It's not
worth maintaining both, and it's much simpler for us to broadcast
instead.
Previously, we only had blanket impls for `KVStore`. However, in order
to enable the use of `dyn KVStore + Send + Sync` instead of a `KVStore`
generic, we here also add the corresponding blanket implementations for
said type signature.
The whole point of full_stack_target is to just expose our entire
API to the fuzzer and see what happens. Sadly, we're really only
exposing a small subset of our API. This improves that by exposing
a handful of other assorted methods from ChannelManager and
PeerManager.
A client node might choose not to handle `Event::BumptTransaction`
events and leave bumping / Anchor output spending to a trusted
counterparty.
However, `Event::BumptTransaction` currently doesn't offer any clear
indication what channel and/or counterparty it is referring to. In order
to allow filtering these events, we here expose the `channel_id` and
`counterparty_node_id` fields.
This exposes details around pending HTLCs in ChannelDetails. The state
of the HTLC in the state machine is also included, so it can be
determined which protocol message the HTLC is waiting for to advance.
While this isn't expected to materially improve performance, it
does get us ahash 0.8, which allows us to reduce fuzzing
randomness, making our fuzzers much happier.
Sadly, by default `ahash` no longer tries to autodetect a
randomness source, so we cannot simply rely on `hashbrown` to do
randomization for us, but rather have to also explicitly depend on
`ahash`.
In the next commit we'll bump the `hashbrown` version, which no
longer randomizes its hasher by default. Thus, we'll need to call
a different constructor in no-std builds from std builds.
Here we do a quick prefactor to use wrappers for `FromIterator`
constructors instead of calling the tables directly to make the
version bump changeset smaller.

As we've added more and more configuration parameters which change
our behavior, we're increasingly missing coverage in the general
`full_stack_target` fuzzer. Sadly, a reachable `unwrap` slipped in
uncaught that should have been stopped by the `full_stack_target`.
Here, we update the `full_stack_target` fuzzer to read a full
config object to substantially increase coverage.
We use these params for our HubPreferentialScorer and without these
utility functions then we have to manually do this and calculate which
is the source and which is the target node.
