When we receive an error message from a peer, it can indicate a

check that the counterparty who sends us such a message is the
counterparty with whom we have the channel, allowing any
connected peer to make us force-close any channel we have as long
as they know the channel id.

This commit simply changes the force-close logic to check that the
sender matches the channel's counterparty node_id, though as noted
in #105, we eventually need to change the indexing anyway to allow
absurdly terrible peers to open channels with us.

convert the Rust-returned concrete Rust type to the C trait struct),

[bindings] Use consistent imports for MessageSendEvents traits

Our bindings generator is braindead with respect to the idents
used in a trait definition - it treats them as if they were used
where the trait is being used, instead of where the trait is
defined. Thus, if the idents used in a trait definition are not
also imported the same in the files where the traits are used, we
will claim the idents are bogus.

I spent some time trying to track the TypeResolvers globally
through the entire conversion run so that we could use the original
file's TypeResolver later when using the trait, but it is somewhat
of a lifetime mess. While likely possible, import consistency is
generally the case anyway, so unless it becomes more of an issue in
the future, it likely makes the most sense to just keep imports
consistent.

around `MessageSendEvent` and `MessageSendEventsProvider`.
