This commit introduces a new field `invoice_msat` to the htlc_accepted
hook. If this field is specified it will replace the amount of the
invoice that belongs to the payment_hash of the HTLC on internal checks.
This is useful in scenarios where we actually expect a smaller amount
than initially specified in an invoice.
Changelog-Changed: Plugins: `htlc_accepted` hook can now override the
expected total amount of the invoice that belongs to the HTLC.

Adds `expected_msat_override` to the `invoice_check_payment` check. If
it's set, it will be used to override the invoice amount as the expected
amount of the payment check.
This enables us to charge a different amount for a payment than the
amount stated on the invoice.

This message is supposed to include the msat amount received. But this is
obviously per-HTLC, and we hacked it to use the value for the first one.
And we add logging whenever we fail an HTLC set, since we removed logging
by not calling failmsg_incorrect_or_unknown() (which, now, no longer needs
to log).

This has the benefit of being shorter, as well as more reliable (you
will get a link error if we can't print it, not a runtime one!).

peer_htlcs has become a bit of a dumping ground: move listforwards
etc to its own file.
Also move `struct channel_info` from peer_htlcs.h to channel.h where
it more logically belongs.

Clean these up: they were debug logs, but we want to pass this information
back for self-payments.
Also fixes "Attept" typo which altered tests!

And turn "" includes into full-path (which makes it easier to put
config.h first, and finds some cases check-includes.sh missed
previously).
config.h sets _GNU_SOURCE which really needs to be done before any
'#includes': we mainly got away with it with glibc, but other platforms
like Alpine may have stricter requirements.

This will allow nodes (with log-level=debug) to gather how many payments
are made without payment_secrets. We need to know this so we know when
we can make them compulsory.

The current plan for coin movements involves tagging
origination/destination htlc's with a separate tag from 'routed' htlcs
(which pass through our node). In order to do this, we need a persistent flag on
incoming htlcs as to whether or not we are the final destination.
Unfortunately the invoice_payment_hook can give us a failcode, so I simply
restrict it to the two sensible ones.

Changelog-deprecated: plugins: invoice_payment_hook "failure_code" only handles simple cases now, use "failure_message".
We tag them with specific versions when they're experimental,
but do a poor job of cleaning them up (and thus ensuring they're
checked!) afterwards.

The invoice_try_pay code now takes a set, rather than a single htlc, but
it's basically the same thing.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This isn't plumbed in yet, but the idea is that every htlc gets put
into a "set" and then we process them once the set is satisfied. For
the !EXPERIMENTAL_FEATURES, the set is simply always size 1.
